Tech entrepreneur/blogger Anil Dash has been critical of AI browsers like ChatGPT Atlas. (He's written that Atlas "substitutes its own AI-generated content for the web, but it looks like it's showing you the web," while its prompt-based/command-line interface resembles a clunky text adventure, and it's true purpose seems to be ingesting more training data.)

And at the Mozilla Festival in Spain, "Virtually everyone shared some version of what I'd articulated as the majority view on AI, which is approximately that LLMs can be interesting as a technology, but that Big Tech, and especially Big AI, are decidedly awful and people are very motivated to stop them from committing their worst harms upon the vulnerable."

But... Another reality that people were a little more quiet in acknowledging, and sometimes reluctant to engage with out loud, is the reality that hundreds of millions of people are using the major AI tools every day... I don't know why today's Firefox users, even if they're the most rabid anti-AI zealots in the world, don't say, "well, even if I hate AI, I want to make sure Firefox is good at protecting the privacy of AI users so I can recommend it to my friends and family who use AI"...

My personal wishlist would be pretty simple:

* Just give people the "shut off all AI features" button. It's a tiny percentage of people who want it, but they're never going to shut up about it, and they're convinced they're the whole world and they can't distinguish between being mad at big companies and being mad at a technology so give them a toggle switch and write up a blog post explaining how extraordinarily expensive it is to maintain a configuration option over the lifespan of a global product.

* Market Firefox as "The best AI browser for people who hate Big AI". Regular users have no idea how creepy the Big AI companies are — they've just heard their local news talk about how AI is the inevitable future. If Mozilla can warn me how to protect my privacy from ChatGPT, then it can also mention that ChatGPT tells children how to self-harm, and should be aggressive in engaging with the community on how to build tools that help mitigate those kinds of harms — how do we catalyze that innovation?

* Remind people that there isn't "a Firefox" — everyone is Firefox. Whether it's Zen, or your custom build of Firefox with your favorite extensions and skins, it's all part of the same story. Got a local LLM that runs entirely as a Firefox extension? Great! That should be one of the many Firefoxes, too. Right now, so much of the drama and heightened emotions and tension are coming from people's (well... dudes') egos about there being One True Firefox, and wanting to be the one who controls what's in that version, as an expression of one set of values. This isn't some blood-feud fork, there can just be a lot of different choices for different situations. Make it all work.

Mozilla announced on Thursday that it is building an AI Window for Firefox, a new opt-in browsing mode that will let users interact with an AI assistant and chatbot. The feature will become one of three browsing experiences in Firefox alongside the existing classic and private windows. Users will be able to select which AI model they want to use in the AI Window, according to a post on the Mozilla Connect forum.

The company opened a waitlist for users who want to receive updates and be among the first to test the feature. Mozilla described the AI Window as an "intelligent and user-controlled space" that it is developing in the open through community feedback. Users who try the feature and decide against it can switch it off entirely.

BrianFagioli writes: Mozilla has released Firefox 145.0, and the standout change in this version is the official end of support for 32-bit Linux systems. Users on 32-bit distributions will no longer receive updates and are being encouraged to switch to the 64-bit build to continue getting security patches and new features. While most major Linux distributions have already moved past 32-bit support, this shift will still impact older hardware users and lightweight community projects that have held on to 32-bit for the sake of performance or preservation.

The rest of the update introduces features such as built-in PDF comments, improved fingerprinting resistance for private browsing, tab group previews, password management in the sidebar, and minor UI refinements. Firefox also now compresses local translation models with Zstandard to reduce storage needs. But the end of 32-bit Linux support is the change that will leave the biggest mark, signaling another step toward a web ecosystem firmly centered on 64-bit computing.

"The Firefox brand is getting a refresh and you get the first look," says a new web page at Firefox.com. "Kit's our new mascot and your new companion through an internet that's private, open and actually yours."

Slashdot reader BrianFagioli believes the new mascot "is meant to communicate that message in a warmer, more relatable way."

And Firefox is already selling shirts with Kit over the pocket (as well as stickers)...

For more than a decade, the nonprofit Common Crawl "has been scraping billions of webpages to build a massive archive of the internet," notes the Atlantic, making it freely available for research. "In recent years, however, this archive has been put to a controversial purpose: AI companies including OpenAI, Google, Anthropic, Nvidia, Meta, and Amazon have used it to train large language models.

"In the process, my reporting has found, Common Crawl has opened a back door for AI companies to train their models with paywalled articles from major news websites. And the foundation appears to be lying to publishers about this — as well as masking the actual contents of its archives..." Common Crawl's website states that it scrapes the internet for "freely available content" without "going behind any 'paywalls.'" Yet the organization has taken articles from major news websites that people normally have to pay for — allowing AI companies to train their LLMs on high-quality journalism for free. Meanwhile, Common Crawl's executive director, Rich Skrenta, has publicly made the case that AI models should be able to access anything on the internet. "The robots are people too," he told me, and should therefore be allowed to "read the books" for free. Multiple news publishers have requested that Common Crawl remove their articles to prevent exactly this use. Common Crawl says it complies with these requests. But my research shows that it does not.

I've discovered that pages downloaded by Common Crawl have appeared in the training data of thousands of AI models. As Stefan Baack, a researcher formerly at Mozilla, has written, "Generative AI in its current form would probably not be possible without Common Crawl." In 2020, OpenAI used Common Crawl's archives to train GPT-3. OpenAI claimed that the program could generate "news articles which human evaluators have difficulty distinguishing from articles written by humans," and in 2022, an iteration on that model, GPT-3.5, became the basis for ChatGPT, kicking off the ongoing generative-AI boom. Many different AI companies are now using publishers' articles to train models that summarize and paraphrase the news, and are deploying those models in ways that steal readers from writers and publishers.

Common Crawl maintains that it is doing nothing wrong. I spoke with Skrenta twice while reporting this story. During the second conversation, I asked him about the foundation archiving news articles even after publishers have asked it to stop. Skrenta told me that these publishers are making a mistake by excluding themselves from "Search 2.0" — referring to the generative-AI products now widely being used to find information online — and said that, anyway, it is the publishers that made their work available in the first place. "You shouldn't have put your content on the internet if you didn't want it to be on the internet," he said. Common Crawl doesn't log in to the websites it scrapes, but its scraper is immune to some of the paywall mechanisms used by news publishers. For example, on many news websites, you can briefly see the full text of any article before your web browser executes the paywall code that checks whether you're a subscriber and hides the content if you're not. Common Crawl's scraper never executes that code, so it gets the full articles.

Thus, by my estimate, the foundation's archives contain millions of articles from news organizations around the world, including The Economist, the Los Angeles Times, The Wall Street Journal, The New York Times, The New Yorker, Harper's, and The Atlantic.... A search for nytimes.com in any crawl from 2013 through 2022 shows a "no captures" result, when in fact there are articles from NYTimes.com in most of these crawls.
"In the past year, Common Crawl's CCBot has become the scraper most widely blocked by the top 1,000 websites," the article points out...

Long-time Slashdot reader AmiMoJo shared this report from Linuxiac: The Japanese branch of Mozilla's Support Mozilla (SUMO) community — responsible for localizing and maintaining Japanese-language support documentation for Firefox and other Mozilla products (consisting of Japanese native speakers) — has officially disbanded after more than two decades of voluntary work...

SUMO, short for Support Mozilla, is the umbrella project for Mozilla's user support platform, support.mozilla.org, that brings together volunteers and contributors worldwide who translate, maintain, and update documentation, tutorials, and troubleshooting guides for Firefox, Thunderbird, and other Mozilla products... According to marsf, the long-time locale leader of the Japanese SUMO team, the decision to disband was triggered by the recent introduction of an automated translation system known as Sumobot. Deployed on October 22, the bot began editing and approving Japanese Knowledge Base articles without community oversight.
The article notes marsf's complaints in a post to the SUMO discussion forum, including the fact that the new automated system automatically approved machine-translated content with only a 72-hour window for human review. As a result, more than 300 Knowledge Base articles were overwritten on the production server, which marsf called "mass destruction of our work."

BrianFagioli shares a report from NERDS.xyz: Mozilla is testing a new Firefox feature that delivers direct results inside the address bar instead of forcing users through a search results page. The company says the feature will use a privacy framework called Oblivious HTTP, encrypting queries so that no single party can see both what you type and who you are. Some results could be sponsored, but Mozilla insists neither it nor advertisers will know user identities. The system is starting in the U.S. and may expand later if performance and privacy benchmarks are met. Further reading: Mozilla to Require Data-Collection Disclosure in All New Firefox Extensions

"Mozilla is introducing a new privacy framework for Firefox extensions that will require developers to disclose whether their add-ons collect or transmit user data..." reports the blog Linuxiac: The policy takes effect on November 3, 2025, and applies to all new Firefox extensions submitted to addons.mozilla.org. According to Mozilla's announcement, extension developers must now include a new key in their manifest.json files. This key specifies whether an extension gathers any personal data. Even extensions that collect nothing must explicitly state "none" in this field to confirm that no data is being collected or shared.

This information will be visible to users at multiple points: during the installation prompt, on the extension's listing page on addons.mozilla.org, and in the Permissions and Data section of Firefox's about:addons page. In practice, this means users will be able to see at a glance whether a new extension collects any data before they install it.

Mozilla is testing a free, built-in VPN for Firefox that routes traffic through Mozilla-managed servers directly in the browser. The Register reports: According to a staff post on Mozilla Connect, the company's idea-sharing platform, Firefox VPN is still an experimental feature in the early stages of development, but users will be selected at random to test it "over the next few months." Moz describes the feature as one that will sit beside the search bar on Firefox, routing web traffic through a Mozilla-managed VPN server, concealing the user's real IP address while adding a layer of encryption to their communications. Firefox VPN is a different project entirely from Mozilla VPN, a separate, paid-for product. The Firefox version will be free to use and confined to the browser itself, while Mozilla VPN can be used by up to five devices at a time.

The Moz staffer on the product team who announced the feature said of the upcoming beta test: "We'll start simple, then gradually add new capabilities while learning how it impacts browsing, usage, and overall satisfaction. "Our long-term vision is ambitious: to build the best VPN-integrated browser on the market." In response to feedback, the staffer noted that while it will be a desktop browser feature first, "mobile is definitely a natural next step."

"California Governor Gavin Newsom signed the 'California Opt Me Out Act', which will require web browsers to include an easy, universal way for users to opt out of data collection and sales," reports the blog 9to5Mac: [The law] requires browsers to provide a clear, one-click mechanism for Californians to opt out of data sharing across websites. The bill reads: "A business shall not develop or maintain a browser that does not include functionality configurable by a consumer that enables the browser to send an opt-out preference signal to businesses with which the consumer interacts through the browser...." Californians will need patience, though, as the law doesn't take effect until January 1, 2027.
Americans in some states — including California, Texas, Colorado, New Jersey and Maryland — "have the option to make those opt-out demands automatic whenever they surf the web," reports the Washington Post. "But they can only do so if they use small browsers that voluntarily offer that option, such as DuckDuckGo, Firefox and Brave. What's new in California's law is that all browsers must give people the same option." That means soon in California, just using Google's Chrome, Apple's Safari and Microsoft's Edge can command companies not to sell your data or pass it along for ad targeting... It's an imperfect but potent and simple way to flex privacy rights — and becomes even more powerful with another simple privacy measure in California. Starting on January 1, California residents can fill out an online form once to completely and repeatedly wipe their data from hundreds of data brokers that package your personal information for sale.
But their article also suggests other ways readers can "try a one-click privacy option now."

• "[S]ome national companies respect one-click privacy opt-out requests from everyone... This happens automatically if you use DuckDuckGo and Brave. You need to change a setting with Firefox."

• "Download Privacy Badger: The software from the Electronic Frontier Foundation, a consumer privacy advocacy group, works in the background to order websites not to sell information they're collecting about you."

• "Use Permission Slip from Consumer Reports. Give the app basic information, and it will help you do much of the legwork to tell companies not to sell your information or to delete it, if you have the right to do so."

Mozilla Firefox's new "Shake to Summarize" feature earned a spot on TIME's Best Inventions of 2025, allowing users to shake their phone to instantly summarize long web pages. Anthony Enzor-DeMeo, general manager of Firefox, calls it a "testament to the incredible work of our UX, design, product, and engineering teams who brought this innovation to life." Neowin reports: Shake to summarize works exactly how you suspect: you physically shake your phone to generate a summary of a long article. This can be quite handy if you are trying to get the gist of a long read without scrolling through the whole thing. Other ways to activate the feature include tapping the thunderbolt icon in the address bar and selecting "Summarize Page" from the three-dot menu.

For now, the feature is limited to iOS users in the US with their system set to English, but Mozilla promises an Android version is in the works. If you have an iPhone 15 Pro or newer running iOS 26, Apple Intelligence generates the summaries on the device. For older iPhones or those on earlier iOS versions, the page text is sent to Mozilla's servers for processing. You can view the full list of TIME's "Special Mentions" here.

An anonymous reader shared this report from the blog Linuxiac: In a somewhat unexpected move, Cloudflare has announced its sponsorship of the Ladybird browser, an independent (still-in-development) open-source initiative aimed at developing a modern, standalone web browser engine.

It's a project launched by GitHub's co-founder and former CEO, Chris Wanstrath, and tech visionary Andreas Kling. It's written in C++, and designed to be fast, standards-compliant, and free of external dependencies. Its main selling point? Unlike most alternative browsers today, Ladybird doesn't sit on top of Chromium or WebKit. Instead, it's building a completely new rendering engine from scratch, which is a rare thing in today's web landscape. For reference, the vast majority of web traffic currently runs through engines developed by either Google (Blink/Chromium), Apple (WebKit), or Mozilla (Gecko).

The sponsorship means the Ladybird team will have more resources to accelerate development. This includes paying developers to work on crucial features, such as JavaScript support, rendering improvements, and compatibility with modern web applications. Cloudflare stated that its support is part of a broader initiative to keep the web open, where competition and multiple implementations can drive enhanced security, performance, and innovation.
The article adds that Cloudflare also chose to sponsor Omarchy, a tool that runs on Arch and sets up and configures a Hyprland tiling window manager, along with a curated set of defaults and developer tools including Neovim, Docker, and Git.

"We've decided to support image-based search," announced the product manager for Firefox Search. Powered by the AI-driven Google Lens search technology, they promise the new feature offers "a frictionless, fast, and a curiosity-sparking way to (as Google puts it) 'search what you see'." With just a right-click on any image, you'll be able to:

- Find similar products, places, or objects
- Copy, translate, or search text from images
- Get inspiration for learning, travel, or shopping

Look for the new "Search Image with Google Lens" option in your right-click menu (tagged with a NEW badge at first). This is a desktop-only feature, and it will start gradually rolling out worldwide. Note: Google must be set as your default search engine for this feature to appear.

We'll be listening closely to your feedback as we roll it out. Some of the things we're wondering about:

Does the placement in the context menu align with your expectations?
Would you prefer the option to choose your visual search provider?
Where else would you like entry points to visual search (e.g. when you open a new tab, in the address bar, on mobile devices, etc.)

We can't wait to hear your thoughts as the rollout begins!
Some thoughts from WebProNews: Mozilla emphasizes that this is an opt-in feature, giving users control over activation, which aligns with the company's longstanding commitment to privacy and user agency.

Yet, for industry observers, this partnership with Google raises intriguing questions about competitive dynamics in the browser space, where Firefox has historically positioned itself as an independent alternative to Chrome... This move comes at a time when browsers are increasingly becoming platforms for AI-driven enhancements, as evidenced by recent updates in competitors like Microsoft's Edge, which integrates Copilot AI. Mozilla's decision to leverage Google Lens rather than developing an in-house solution could be seen as a pragmatic step to accelerate feature parity, especially given Firefox's smaller market share. Insiders note that by tapping into established technologies, Mozilla can focus resources on core strengths like privacy protections, potentially attracting users disillusioned with data-heavy ecosystems... While mobile users might feel left out, the phased rollout over the next few weeks allows for feedback loops through community channels, a hallmark of Mozilla's open-source ethos.

Data from similar integrations in other browsers suggests visual search can boost engagement by 15-20%, per industry reports, though Mozilla has not disclosed specific metrics yet... Looking ahead, Mozilla's strategy appears geared toward incremental innovations that bolster user retention without alienating its privacy-focused base. If successful, this could help Firefox claw back some ground against Chrome's dominance, estimated at over 60% market share. For now, the feature's gradual deployment invites ongoing dialogue, underscoring Mozilla's community-driven model in an industry often criticized for top-down decisions.

The blog OMG Ubuntu notes that Microsoft Copilot chatbot support has been added in the latest Firefox Nightly builds. "Firefox's sidebar already offers access to popular chatbots, including OpenAI's ChatGPT, Anthropic's Claude, Le Chat's Mistral and Google's Gemini. It previously offered HuggingChat too." As the testing bed for features Mozilla wants to add to stable builds (though not all make it — eh, rounded bottom window corners?), this is something you can expect to find in a future stable update... Copilot in Firefox offers the same features as other chatbots: text prompts, upload files or images, generate images, support for entering voice prompts (for those who fancy their voice patterns being analysed and trained on). And like those other chatbots, there are usage limits, privacy policies, and (for some) account creation needed. In testing, Copilot would only generate half a summary for a webpage, telling me it was too long to produce without me signing in/up for an account.

On a related note, Mozilla has updated stable builds to let third-party chatbots summarise web pages when browsing (in-app callout alerts users to the 'new' feature). Users yet to enable chatbots are subtly nudged to do so each time they right-click on web page. [Between "Take Screenshot" and "View Page Source" there's a menu option for "Ask an AI Chatbot."] Despite making noise about its own (sluggish, but getting faster) on-device AI features that are privacy-orientated, Mozilla is bullish on the need for external chatbots.
The article suggests Firefox wants to keep up with Edge and Chrome (which can "infuse first-party AI features directly.") But it adds that Firefox's nightly build is also testing some non-AI features, like new task and timer widgets on Firefox's New Tab page. And "In Firefox Labs, there are is an option to enable JPEG XL support, a super-optimised version of JPEG that is gaining traction (despite Google's intransigence).

Other Firefox news:

• There's good news "for users still clinging to Windows 7," writes the Register. Support for Firefox Extended Support Release 115 "is being extended until March 2026."

• Google "can keep paying companies like Mozilla to make Google the default search engine, as long as these deals aren't exclusive anymore," reports the blog It's FOSS News. (The judge wrote that "Cutting off payments from Google almost certainly will impose substantial — in some cases, crippling — downstream harms to distribution partners..." according to CNBC — especially since the non-profit Mozilla Foundation gets most of its annual revenue from its Google's search deal.)

• Don't forget you can now search your tabs, bookmarks and browsing history right from the address bar with keywords like @bookmarks, @tabs, and @history. (And @actions pulls up a list of actions like "Open private window" or "Restart Firefox").

Mozilla announced today that they will end 32-bit Linux support for Firefox in 2026, with version 144 being the last release and ESR 140 as the fallback option. Phoronix reports: Firefox has continued providing 32-bit Linux binaries even with most other web browsers and operating systems going all-in on x86_64 support. But given that 32-bit Linux support is waning by distributions and the vast majority of distributions aren't even shipping i686 install images anymore, they will be removing 32-bit Linux builds in 2026.

"Good news, everyone! The new version of Mozilla's browser now makes even more extensive use of AI," writes the Register, "providing summaries of linked content and offering developers the ability to add LLM support to extensions." Firefox 142 brings some visible shininess, but due to the combination of regional restrictions and Mozilla's progressive rollout system, not everybody can see all the features just yet... Not geofenced but subject to phased rollout are link previews, for various native-English-speaking regions. Hover over, long-press, or right-click a link and pick Preview Link, and a summary should appear. Mozilla's summary says: "Previews can optionally include AI-generated key points, which are processed on your device to protect your privacy."
"Link Previews is gradually rolling out to ensure performance and quality," Firefox says in their release notes, "and is now available in en-US, en-CA, en-GB, en-AU for users with more than 3 GB of available RAM." (The notes also add a welcome for "the developers who contributed their first code change to Firefox in this release, 20 of whom were brand new volunteers!")

The Register notes that Firefox 142 also gives developers the ability to add LLM support to extensions using wllama, a Wasm binding interfacing with llama.cpp, which lets you run Meta's Llama LLM and other models, locally or in the cloud.

darwinmac writes: Firefox 141 rolled out a shiny new AI-powered smart tab grouping feature (it tries to auto-organize your tabs using a local model), but it turns out the local "Inference" process that powers it is acting like an energy-sucking monster. Users are reporting massive CPU spikes and battery drain and calling the feature "garbage" that's ruining their browsing experience.

Plasma 6.4.5 is coming September 9th, reports Neowin. But they also report that the KDE team is already focusing on other upcoming release: Starting with KDE Frameworks, KDE's collection of foundational libraries, version 6.18 promises to let you do something with that "dumb" Microsoft Copilot key found on many new laptops. The developers will soon allow you to set up keyboard shortcuts using this new key, and the team plans to let you remap it to another key in the future. If you're curious, one user on KDE's bug tracker noted that on GNOME, the key combination shows up as "Meta+Shift+Touchpad Disable" and is fully remappable...

When you try to install a Flatpak from a website like Flathub in Plasma 6.5 [coming in October], Discover now has proper support for flatpak+https:// URLs, so it opens automatically. 6.5 is also bringing a much stricter window activation policy on Wayland to stop applications from rudely stealing your focus. And now, when you mute your microphone with a shortcut, the "Mute Microphone" button will mute all input sources, not just the active one.

Since Firefox does not block the system from sleeping during a download, the Plasma Browser Integration extension for Firefox has gotten an update to handle that job itself.

AI startup Perplexity is deploying undeclared web crawlers that masquerade as regular Chrome browsers to access content from websites that have explicitly blocked its official bots, according to a Cloudflare report published Monday. When Perplexity's declared crawlers encounter robots.txt restrictions or network blocks, the company switches to a generic Mozilla user agent that impersonates "Chrome/124.0.0.0 Safari/537.36" running on macOS, the web infrastructure firm reported.

Cloudflare engineers tested the behavior by creating new domains with robots.txt files prohibiting all automated access. Despite the restrictions, Perplexity provided detailed information about the protected content when queried, while the stealth crawler generated 3-6 million daily requests across tens of thousands of domains. The undeclared crawler rotated through multiple IP addresses and network providers to evade detection.

Mozilla will ship WebGPU support in Firefox 141 when the browser launches July 22, bringing graphics processing capabilities that Chrome users have had since 2023. The initial release supports Windows only, with Mac, Linux, and Android planned for the coming months.

WebGPU provides web content direct access to graphics processors for high-performance computation and rendering in games and complex 3D applications. Chrome gained WebGPU support with version 113 in 2023, while Safari 26 is expected to add the feature this fall. Firefox's implementation uses the WGPU Rust crate, which translates web requests into native commands for Direct3D 12, Metal, or Vulkan.
