Firefox is now looking quite different for most users after Mozilla started rolling out a redesign to everyone across desktop and mobile. The new look may not be too much of a surprise for some, though. Beta testers have been able to check it out through the Nightly version of the browser for the last few months. Mozilla says it updated Firefox's themes, icons and colors to modernize it in line with features it has added recently, such as a single off switch for generative AI tools. The redesign itself brings more features to Firefox, as well as the return of compact mode, a much-requested option that Mozilla previously nixed.

Firefox says it will keep supporting uBlock Origin even as Microsoft Edge and other Chromium browsers phase it out under Manifest V3. Firefox recently announced via Bluesky post: "Our support for uBlock Origin isn't going anywhere." The moment comes in response to news that Microsoft Edge is soon going to lock out uBlock Origin and other ad-blocking extensions that run on Manifest V2 architecture. Once Microsoft Edge moves to Manifest V3, ad-blocking extensions won't have access to the functions needed to properly identify and block ads that occur while browsing websites and watching videos.

Mozilla Used Anthropic's Mythos to Find and Fix 271 Bugs in Firefox The Firefox team doesn't think emerging AI capabilities will upend cybersecurity long term, but they warn that software developers are likely in for a rocky transition. Amid a raging debate over the impact that new AI models will have on cybersecurity, Mozilla said on Tuesday that its Firefox 150 browser release this week includes protections for 271 vulnerabilities identified using early access to Anthropic's Mythos Preview . The Firefox team says that it has taken resources and discipline to adjust to the firehose of bugs that new AI tools can uncover, but that this big lift is necessary for the security of Mozilla's users, given that the capabilities will inevitably be in attackers' hands soon. Both Anthropic and OpenAI have announced new AI models in recent weeks that the companies say have advanced cybersecurity capabilities that could represent a turning point in how defenders--and, crucially, attackers--find vulnerabilities and misconfigurations in software systems. With this in mind, the companies have so far only done limited private releases of their new models, and both have also convened industry working groups meant to assess the advances and strategize.

Plus: Anthropic's new tools are freaking out the markets Every time OpenAI, Google, or Anthropic drops a new frontier large language model, the AI community holds its breath. It doesn't exhale until METR, an AI research nonprofit whose name stands for "Model Evaluation & Threat Research," updates a now-iconic graph that has played a major role in the AI discourse since it was first released in March of last year. The graph suggests that certain AI capabilities are developing at an exponential rate, and more recent model releases have outperformed that already impressive trend. That was certainly the case for Claude Opus 4.5, the latest version of Anthropic's most powerful model, which was released in late November. In December, METR announced that Opus 4.5 appeared to be capable of independently completing a task that would have taken a human about five hours--a vast improvement over what even the exponential trend would have predicted. But the truth is more complicated than those dramatic responses would suggest.

Like practically every other tech company under the sun, Mozilla has been jamming generative AI features into its products . The organization has now acknowledged that not everyone wants things like chatbots in the Firefox sidebar, so it's giving you the option to turn off all of that. On February 24 (or earlier in Firefox Nightly builds), Mozilla will roll out Firefox 148, which will include an AI controls section in the desktop browser settings. From here, you'll be able to block current and future generative AI features, or only enable select tools. At the jump, you'll have the option to disable (or enable) chatbots in the sidebar, automated translations and alt text generation for PDFs.

PCWorld reports that Mozilla's new CEO Anthony Enzor-DeMeo plans to integrate AI features into Firefox while maintaining user choice to disable them. This strategic shift addresses Firefox's stagnant market share and aims to compete with AI-centric browsers without compromising privacy principles. The optional AI implementation reflects Mozilla's commitment to transparency and user control in an increasingly competitive browser landscape. Mozilla recently confirmed that it's shifting gears and bringing AI features to its Firefox browser. However, according to the newly appointed CEO Anthony Enzor-DeMeo, the AI features will always be optional and possible to switch off completely.
