Phoronix staged "a showdown" between Firefox and Chrome, testing them both on an Intel Panther Lake laptop running Ubuntu 26.04. JetStream 3.0 was announced at the end of March as the latest major web browser benchmark. This updated version of JetStream is focused on intensive portions of modern JavaScript and WebAssembly web applications... Google Chrome 147 came in at 1.47x the performance of Mozilla Firefox 149. A very strong showing for Google's web browser and to not much surprise Google engineers have been heavily involved in JetStream 3 as part of its open governance model. Chrome debuts very well on JetStream 3 while it will be interesting to see what optimizations Mozilla engineers pursue in the months ahead...

In the recent Speedometer 3.1 benchmark update that is focused on browser responsiveness, Chrome was at 1.24x the performance of Firefox... Firefox picked up wins in the MotionMark and StyleBench browser benchmarks. Google Chrome meanwhile continued to dominate in the JavaScript heavy benchmarks... In some of the WebAssembly benchmarks, there was at least some healthy competition between Firefox and Chrome on Linux.

Across the web browser benchmarks, the Core Ultra X7 358H power consumption came in at 11.44 Watts on average for Chrome and 11.74 Watts for Firefox. Quite close. The slight CPU power difference may come down to the CPU usage with Chrome coming in slightly lower at 8.13% on average to 8.35% with Firefox. Chrome also came in at slightly lower memory consumption across all the benchmarks with total memory usage on average at 4.67GB to Firefox at 4.83GB.

BrianFagioli writes: Mozilla is accusing Microsoft of stacking the deck against Firefox, arguing that design choices in Windows steer users toward Edge even when they explicitly choose another browser. According to Mozilla, parts of Windows still open links in Edge regardless of the default browser setting, including results from the taskbar search and links launched from apps like Outlook and Teams. Mozilla says this means Firefox often never even gets the opportunity to handle those links, which quietly shifts user activity back into Microsoft's ecosystem.

The company also points to Microsoft's aggressive rollout of Copilot as another example of platform power being used to push Microsoft services. Copilot appeared pinned to the taskbar, arrived automatically on many systems with Microsoft 365, and even received a dedicated keyboard key on some laptops. Mozilla argues that when the maker of the dominant desktop operating system promotes its own browser and AI tools at the system level, it becomes far harder for independent browsers like Firefox to compete.

An anonymous reader quotes a report from Ars Technica: AOMedia Video 1 (AV1) was invented by a group of technology companies to be an open, royalty-free alternative to other video codecs, like HEVC/H.265. But a lawsuit that Dolby Laboratories Inc. filed this week against Snap Inc. calls all that into question with claims of patent infringement. Numerous lawsuits are currently open in the US regarding the use of HEVC. Relevant patent holders, such as Nokia and InterDigital, have sued numerous hardware vendors and streaming service providers in pursuit of licensing fees for the use of patented technologies deemed essential to HEVC.

It's a touch rarer to see a lawsuit filed over the implementation of AV1. The Alliance for Open Media (AOMedia), whose members include Amazon, Apple, Google, Microsoft, Mozilla, and Netflix, says it developed AV1 "under a royalty-free patent policy (Alliance for Open Media Patent License 1.0)" and that the standard is "supported by high-quality reference implementations under a simple, permissive license (BSD 3-Clause Clear License)."

Yet, Dolby's lawsuit filed in the US District Court for the District of Delaware [PDF] alleges that AV1 leverages technologies that Dolby has patented and has not agreed to license for free and without receiving royalties. The filing reads: "[AOMedia] does not own all patents practiced by implementations of the AV1 codec. Rather, the AV1 specification was developed after many foundational video coding patents had already been filed, and AV1 incorporates technologies that are also present in HEVC. Those technologies are subject to existing third-party patent rights and associated licensing obligations." Dolby is seeking a jury trial, a declaration that Dolby isn't obligated to license the patents in questions under FRAND (fair, reasonable, and non-discriminatory) licensing obligations, and for the court to enjoin Snap from further "infringement."

BrianFagioli writes: Mozilla just teamed up with Mila, the Quebec Artificial Intelligence Institute, to push open source AI -- and it feels like a direct response to Big Tech tightening its grip on the space. Instead of relying on closed models, the goal here is to build "sovereign AI" that's more transparent, privacy-focused, and actually under the control of developers and even governments. They're starting with things like private memory for AI agents, which sounds niche but matters if you care about where your data goes. Big question is whether open source can realistically keep up with the billions being poured into proprietary AI, but at least someone's trying to give folks an alternative. "Canada has what it takes to lead on frontier AI that the world can actually trust: the research depth, the values, and the will to do it differently. The next frontier in AI isn't just capability, it is trustworthiness, and Canada is uniquely positioned to lead on both. This partnership is a concrete step in that direction. Open, trustworthy AI isn't a compromise on ambition. It's the higher bar," said Valerie Pisano, president and CEO of Mila.

A free built-in VPN is coming to Firefox on Tuesday, Mozilla announced this week: Free VPNs can sometimes mean sketchy arrangements that end up compromising your privacy, but ours is built from our data principles and commitment to be the world's most trusted browser. It routes your browser traffic through a proxy to hide your IP address and location while you browse, giving you stronger privacy and protection online with no extra downloads. Users will have 50 gigabytes of data monthly in the U.S., France, Germany and U.K. to start. Available in Firefox 149 starting March 24.

We also recently shared that Firefox is the first browser to ship Sanitizer API, a new web security standard that blocks attacks before they reach you [for untrusted HTML XSS vulnerabilities].
"The roadmap for Firefox this year is the most exciting one we've developed in quite a while," says Firefox head Ajit Varma. "We're improving the fundamentals like speed and performance. We're also launching innovative new open standards in Gecko to ensure the future of the web is open, diverse, and not controlled by a single engine.

"At the same time we're prioritizing features that give users real power, choice and strong privacy protections, built in a way that only Firefox can. And as always, we'll keep listening, inviting users to help shape what comes next and giving them more reasons to love Firefox."

Two new features coming next week:

• Split View puts two webpages side by side in one window, making it easy to compare, copy and multitask without bouncing between tabs. Rolling out in Firefox 149 on March 24.

• Tab Notes let you add notes to any tab, another tool to help with multitasking and picking up where you left off. Available in Firefox Labs 149 starting March 24.

And Firefox also released a video this week introducing their new mascot Kit.

"It took Anthropic's most advanced artificial-intelligence model about 20 minutes to find its first Firefox browser bug during an internal test of its hacking prowess," reports the Wall Street Journal. The Anthropic team submitted it, and Firefox's developers quickly wrote back: This bug was serious. Could they get on a call? "What else do you have? Send us more," said Brian Grinstead, an engineer with Mozilla, Firefox's parent organization.

Anthropic did. Over a two-week period in January, Claude Opus 4.6 found more high-severity bugs in Firefox than the rest of the world typically reports in two months, Mozilla said... In the two weeks it was scanning, Claude discovered more than 100 bugs in total, 14 of which were considered "high severity..." Last year, Firefox patched 73 bugs that it rated as either high severity or critical.
A Mozilla blog post calls Firefox "one of the most scrutinized and security-hardened codebases on the web. Open source means our code is visible, reviewable, and continuously stress-tested by a global community." So they're impressed — and also thankful Anthropic provided test cases "that allowed our security team to quickly verify and reproduce each issue." Within hours, our platform engineers began landing fixes, and we kicked off a tight collaboration with Anthropic to apply the same technique across the rest of the browser codebase... . A number of the lower-severity findings were assertion failures, which overlapped with issues traditionally found through fuzzing, an automated testing technique that feeds software huge numbers of unexpected inputs to trigger crashes and bugs. However, the model also identified distinct classes of logic errors that fuzzers had not previously uncovered...

We view this as clear evidence that large-scale, AI-assisted analysis is a powerful new addition in security engineers' toolbox. Firefox has undergone some of the most extensive fuzzing, static analysis, and regular security review over decades. Despite this, the model was able to reveal many previously unknown bugs. This is analogous to the early days of fuzzing; there is likely a substantial backlog of now-discoverable bugs across widely deployed software.
"In the time it took us to validate and submit this first vulnerability to Firefox, Claude had already discovered fifty more unique crashing inputs" in 6,000 C++ files, Anthropic says in a blog post (which points out they've also used Claude Opus 4.6 to discover vulnerabilities in the Linux kernel).

"Anthropic "also rolled out Claude Code Security, an automated code security testing tool, last month," reports Axios, noting the move briefly rattled cybersecurity stocks...

darwinmac writes: Mozilla is working on a huge redesign for its Firefox browser, codenamed "Nova," which will bring pastel gradients, a refreshed new tab page, floating "island" UI elements, and more. "From the mockups, it appears Mozilla took some inspiration from Googles Material You (or at least, the dynamic color extraction part of it) because the browser color accent appears influenced by the wallpaper setting," reports Neowin. "Choosing a mint-green desktop background automatically shifts the top navigation bars to match that exact shade."

Mozilla has a habit of redesigning Firefox every few years. Before "Nova," there was the "Proton" redesign in 2021, the "Photon" redesign in 2017, and the "Australis" redesign in 2014. Nova is still in early development, so it might take a year or two before it appears in an official stable Firefox release. Neowin adds: "Not every redesign project ends well for Mozilla, though. You might remember 2012's Firefox Metro, an ambitious attempt to build a custom browser for Windows 8s touch-first interface. The team built it to operate both as a traditional desktop application and as a touch-optimized Metro app. The whole thing was scrapped in 2014 after two years in development due to a dismally low user adoption rate (a preview version of the software had been released a year earlier on the Aurora channel)."

Mozilla has released Firefox 148 for Windows, macOS and Linux, bringing a new AI Settings section that lets users disable all of the browser's AI-powered features in one click and then selectively re-enable the ones they actually want, such as the local translation tool that works locally rather than in the cloud.

The update also patches more than 50 security vulnerabilities -- none known to be under active exploitation -- over half of which Mozilla classifies as high risk, including five sandbox escape flaws and eight use-after-free bugs in the JavaScript engine that could allow code execution.

Firefox 148 introduces granular AI controls and a global "AI kill switch" that allows users to disable or selectively manage the browser's AI features. Phoronix reports: Among the AI features that can be toggled individually are around translations, image alt text in the Firefox PDF viewer, tab group suggestions, key points in link previews, and AI chatbot providers in the sidebar. Firefox 148 also brings Firefox for Android, support for the Trusted Types API, CSS shape() function support, Sanitizer API support, WebGPU enhancements, and a variety of other changes. Developer chances can be found at developer.mozilla.org. Binaries are available from ftp.mozilla.org.

The Mozilla executive in charge of Firefox says that while some people just want AI tools that are genuinely useful, "We've heard from many who want nothing to do with AI..."

"Listening to our community, alongside our ongoing commitment to offer choice, led us to build AI controls." Starting with Firefox 148, which rolls out on Feb. 24, you'll find a new AI controls section within the desktop browser settings. It provides a single place to block current and future generative AI features in Firefox... This lets you use Firefox without AI while we continue to build AI features for those who want them...

At launch, AI controls let you manage these features individually:

— Translations, which help you browse the web in your preferred language.
— Alt text in PDFs, which add accessibility descriptions to images in PDF pages.
— AI-enhanced tab grouping, which suggests related tabs and group names.
— Link previews, which show key points before you open a link.
— AI chatbot in the sidebar, which lets you use your chosen chatbot as you browse, including options like Anthropic Claude, ChatGPT, Microsoft Copilot, Google Gemini and Le Chat Mistral.

You can choose to use some of these and not others. If you don't want to use AI features from Firefox at all, you can turn on the Block AI enhancements toggle. When it's toggled on, you won't see pop-ups or reminders to use existing or upcoming AI features. Once you set your AI preferences in Firefox, they stay in place across updates... We believe choice is more important than ever as AI becomes a part of people's browsing experiences. What matters to us is giving people control, no matter how they feel about AI.

If you'd like to try AI controls early, they'll be available first in Firefox Nightly.
Some context from The Register It's a refreshingly unsubtle stance, and one that lands just days after a similar bout of AI skepticism elsewhere in browser land, with Vivaldi's latest release leaning away from generative features entirely. CEO Jon von Tetzchner summed up the mood, telling The Register: "Basically, what we are finding is that people hate AI..." Mozilla's kill switch isn't the end of AI in browsers, but it does suggest the hype has met resistance.
When it comes to AI kill switches in browsers, Jack Wallen writes at ZDNet that "Most browsers already offer this feature. With Edge, you can disable Copilot. With Chrome, you can disable Gemini. With Opera, you can disable Aria...."

Mozilla, the nonprofit organization behind the Firefox browser that has spent two decades battling tech giants over control of the internet, is now turning its attention to AI and deploying roughly $1.4 billion in reserves to fund what president Mark Surman calls a "rebel alliance" of startups focused on AI safety, transparency and governance.

The organization released a report Tuesday outlining its strategy to counter the growing dominance of OpenAI and Anthropic, which have raised more than $60 billion and $30 billion respectively from investors and now command valuations of $500 billion and $350 billion. Mozilla Ventures, a fund launched in 2022 with an initial $35 million commitment, has invested in more than 55 companies to date and is exploring raising additional capital.

Surman, who runs the organization from a farm outside Toronto, acknowledged the financial mismatch but said Mozilla is playing the long game. By 2028, he wants Mozilla to be funding a "mainstream" open-source AI ecosystem for developers. The effort faces headwinds from the Trump administration, which has criticized AI safety efforts as "woke AI" and signed an executive order establishing a task force to challenge state AI regulations.

Both GNOME and Firefox are considering disabling middle-click paste by default, arguing it's a confusing, accident-prone X11 relic that dumps clipboard contents without warning. Phoronix reports: A merge request for GNOME's gsettings-desktop-schemas was opened this weekend to disable the primary-paste functionality by default that allows using the middle mouse button for pasting. Jordan Petridis argued in that GNOME pull request that middle-click paste is an "X11'ism" and that the setting could remain for those wanting to opt-in to enabling the functionality [...].

The gsettings set org.gnome.desktop.interface gtk-enable-primary-paste true command would be a way of restoring the primary paste (middle click paste) for those desiring the functionality. The decision over the default has been tasked to GNOME's design team for consideration.

Separately, Mozilla is also considering disabling middle mouse button paste by default too. [...] Another option being considered is having the option to enable/disable it at either the GTK toolkit level or Wayland compositor level.

Long-time Slashdot reader destinyland wonders if "gifts for geeks" is the next big consumer demographic: For this year's holiday celebrations, Hallmark made a special Christmas tree ornament, a tiny monitor displaying screens from the classic video game "Oregon Trail." ("Recall the fun of leading a team of oxen and a wagon loaded with provisions from Missouri to the West....") Top sites and major brands are now targeting the "tech" demographic — including programmers, sysadmins and even vintage game enthusiasts — and when Hallmark and Amazon are chasing the same customers as GitHub and Copilot, you know there's been a strange yet meaningful shift in the culture...

While AI was conquering the world, GitHub published its "Ultimate gift guide for the developer in your life" just as soon as doors opened on Black Friday. So if you're wondering, "Should I push to production on New Year's Eve?" GitHub recommends their new "GitHub Copilot Amazeball," which it describes as "GitHub's magical collectible ready to weigh in on your toughest calls !" Copilot isn't involved — questions are randomly matched to the answers printed on the side of a triangle-shaped die floating in water. "[Y]ou'll get answers straight from the repo of destiny with a simple shake," GitHub promises — just like the Magic 8 Ball of yore. "Get your hands on this must-have collectible and enjoy the cosmic guidance — no real context switching required!" And GitHub's "Gift Guide for Developers" also suggests GitHub-branded ugly holiday socks and keyboard keycaps with GitHub's mascots.

But GitHub isn't the only major tech site with a shopping page targeting the geek demographic. Firefox is selling merchandise with its new mascot. Even the Free Software Foundation has its own shop, with Emacs T-shirts, GNU beanies and a stuffed baby gnu ("One of our most sought-after items ... "). Plus an FSF-branded antisurveillance webcam guard.

Maybe Dr. Seuss can write a new book: "How the Geeks Stole Christmas." Because this newfound interest in the geek demographic seems to have spread to the largest sites of all. Google searches on "Gifts for Programmers" now point to a special page on Amazon with suggestions like Linux crossword puzzles. But what coder could resist a book called " Cooking for Programmers? "Each recipe is written as source code in a different programming language," explains the book's description... The book is filled with colorful recipes — thanks to syntax highlighting, which turns the letters red, blue and green. There are also real cooking instructions, but presented as an array of strings, with both ingredients and instructions ultimately logged as messages to the console...

Some programmers might prefer their shirts from FreeWear.org, which donates part of the proceeds from every sale to its corresponding FOSS project or organization. (There are T-shirts for Linux, Gnome and the C programming language — and even one making a joke about how hard it is to exit Vim.)

But maybe it all proves that there's something for everybody. That's the real heartwarming message behind these extra-geeky Christmas gifts — that in the end, tech is, after all, still a community, with its own hallowed traditions and shared celebrations.

It's just that instead of singing Christmas carols, we make jokes about Vim.

An anonymous reader shared this report from 9to5Linux: After the controversial news shared earlier this week by Mozilla's new CEO that Firefox will evolve into "a modern AI browser," the company now revealed it is working on an AI kill switch for the open-source web browser...

What was not made clear [in Tuesday's comments by new Mozilla CEO Anthony Enzor-DeMeo] is that Firefox will also ship with an AI kill switch that will let users completely disable all the AI features that are included in Firefox. Mozilla shared this important update earlier Thursday to make it clear to everyone that Firefox will still be a trusted web browser.... "...that's how seriously and absolutely we're taking this," said Firefox developer Jake Archibald on Mastodon.

In addition, Jake Archibald said that all the AI features that are or will be included in Firefox will also be opt-in. "I think there are some grey areas in what 'opt-in' means to different people (e.g. is a new toolbar button opt-in?), but the kill switch will absolutely remove all that stuff, and never show it in future. That's unambiguous..."

Mozilla has contacted me shortly after writing the story to confirm that the "AI Kill Switch" will be implemented in Q1 2026."
The article also cites this quote left by Mozilla's new CEO on Reddit:

"Rest assured, Firefox will always remain a browser built around user control. That includes AI. You will have a clear way to turn AI features off. A real kill switch is coming in Q1 of 2026. Choice matters and demonstrating our commitment to choice is how we build and maintain trust."

Mozilla has named Anthony Enzor-DeMeo as its new chief executive, promoting the executive who has spent the past year leading the Firefox browser team and who now plans to make AI central to the company's future.

Enzor-DeMeo announced on Tuesday that an "AI Mode" is coming to Firefox next year. The feature will let users choose from multiple AI models rather than being locked into a single provider. Some options will be open-source models, others will be private "Mozilla-hosted cloud options," and the company also plans to integrate models from major AI companies. Mozilla itself will not train its own large language model.

"We're not incentivized to push one model or the other," Enzor-DeMeo told The Verge. Firefox currently has about 200 million monthly users, a fraction of Chrome's roughly 4 billion, though Enzor-DeMeo insists mobile usage is growing at a decent clip.

He takes over from interim CEO Laura Chambers, who led the company through a major antitrust case and what Mozilla describes as "double-digit mobile growth" in Firefox. Chambers is returning to the Mozilla board of directors. The new CEO has outlined three priorities: ensuring all products give users control over AI features including the ability to turn them off, building a business model around transparent monetization, and expanding Firefox into a broader ecosystem of trusted software. Mozilla VPN integration is planned for the browser next year.

Choosing your browser "is one of the most important digital decisions you can make, shaping how you experience the web, protect your data, and express yourself online," says the Firefox blog. They've urged readers to "take a stand for independence and control in your digital life."

But they also recently polled 8,000 adults in France, Germany, the UK and the U.S. on "how they navigate choice and control both online and offline" (attending in-person events in Chicago, Berlin, LA, and Munich, San Diego, Stuttgart): The survey, conducted by research agency YouGov, showcases a tension between people's desire to have control over their data and digital privacy, and the reality of the internet today — a reality defined by Big Tech platforms that make it difficult for people to exercise meaningful choice online:


— Only 16% feel in control of their privacy choices (highest in Germany at 21%)

— 24% feel it's "too late" because Big Tech already has too much control or knows too much about them. And 36% said the feeling of Big Tech companies knowing too much about them is frustrating — highest among respondents in the U.S. (43%) and the UK (40%)

— Practices respondents said frustrated them were Big Tech using their data to train AI without their permission (38%) and tracking their data without asking (47%; highest in U.S. — 55% and lowest in France — 39%)


And from our existing research on browser choice, we know more about how defaults that are hard to change and confusing settings can bury alternatives, limiting people's ability to choose for themselves — the real problem that fuels these dynamics.

Taken together our new and existing insights could also explain why, when asked which actions feel like the strongest expressions of their independence online, choosing not to share their data (44%) was among the top three responses in each country (46% in the UK; 45% in the U.S.; 44% in France; 39% in Germany)... We also see a powerful signal in how people think about choosing the communities and platforms they join — for 29% of respondents, this was one of their top three expressions of independence online.
"For Firefox, community has always been at the heart of what we do," says their VP of Global Marketing, "and we'll keep fighting to put real choice and control back in people's hands so the web once again feels like it belongs to the communities that shape it."

At TwitchCon in San Diego Firefox even launched a satirical new online card game with a privacy theme called Data War.

Firefox 146 has been released with native fractional scaling support on Wayland -- finally giving Linux users crisp UI rendering. Other new additions include GPU process improvements on macOS, developer-focused CSS features, and broader access to Firefox Labs. Phoronix reports: Firefox 146 also now makes Firefox Labs available to all users, Firefox on macOS now has a dedicated GPU process by default, dropping Direct2D support on Windows, support for compressed elliptic curve points in WebCrypto, and updated the bundled Skia graphics library. Firefox 146 also has some fun developer enhancements like support for the CSS text-decoration-inset property, the @scope rule now being supported, CSS contrast-color() function being available, and several new experimental web features. The release notes and developer changes can be found at their respective links. Release binaries are available at Mozilla.org.

"Fresh from announcing it is building an AI browsing mode in Firefox and laying the groundwork for agentic interactions in the Firefox 145 release, the corp arm of Mozilla is now flexing its AI muscles in the direction of those more likely to care," writes the blog OMG Ubuntu: If you're a developer building AI agents, you can sign up to get early access to Mozilla's TABS API, a "powerful web content extraction and transformation toolkit designed specifically for AI agent builders"... The TABS API enables devs to create agents to automate web interactions, like clicking, scrolling, searching, and submitting forms "just like a human". Real-time feedback and adaptive behaviours will, Mozilla say, offer "full control of the web, without the complexity."

As TABS is not powered by a Mozilla-backed LLM you'll need to connect it to your choice of third-party LLM for any relevant processing... Developers get 1,000 requests monthly on the free tier, which seems reasonable for prototyping personal projects. Complex agentic workloads may require more. Though pricing is yet to be locked in, the TABS API website suggests it'll cost ~$5 per 1000 requests. Paid plans will offer additional features too, like lower latency and, somewhat ironically, CAPTCHA solving so AI can 'prove' it's not a robot on pages gated to prevent automated activities.

Google, OpenAI, and other major AI vendors offer their own agentic APIs. Mozilla is pitching up late, but it plans to play differently. It touts a "strong focus on data minimisation and security", with scraped data treated ephemerally — i.e., not kept. As a distinction, that matters. AI agents can be given complex online tasks that involve all sorts of personal or sensitive data being fetched and worked with.... If you're minded to make one, perhaps without a motivation to asset-strip the common good, Mozilla's TABS API look like a solid place to start.

Phoronix's Michael Larabel reports: A 21 year old bug report requesting support of the XDG Base Directory specification is finally being addressed by Firefox. The Firefox 147 release should respect this XDG specification around where files should be positioned within Linux users' home directory.

The XDG Base Directory specification lays out where application data files, configuration files, cached assets, and other files and file formats should be positioned within a user's home directory and the XDG environment variables for accessing those locations. To date Firefox has just positioned all files under ~/.mozilla rather than the likes of ~/.config and ~/.local/share.

Mozilla is officially ending its partnership with Onerep after more than a year of controversy over the company's founder secretly running people-search and data-broker sites. Monitor Plus will be discontinued by December 2025, existing subscribers will receive prorated refunds, and Mozilla says it will focus on privacy tools it fully controls. KrebsOnSecurity reports: In a statement published Tuesday, Mozilla said it will soon discontinue Monitor Plus, which offered data broker site scans and automated personal data removal from Onerep. "We will continue to offer our free Monitor data breach service, which is integrated into Firefox's credential manager, and we are focused on integrating more of our privacy and security experiences in Firefox, including our VPN, for free," the advisory reads.

Mozilla said current Monitor Plus subscribers will retain full access through the wind-down period, which ends on Dec. 17, 2025. After that, those subscribers will automatically receive a prorated refund for the unused portion of their subscription. "We explored several options to keep Monitor Plus going, but our high standards for vendors, and the realities of the data broker ecosystem made it challenging to consistently deliver the level of value and reliability we expect for our users," Mozilla statement reads.
