Mobile browsing hasn’t kept up with how people actually use their phones. Right now, even basic tasks can feel harder than they should. Finding what you need can mean scrolling through ads and filler content, keeping track of too many tabs, or thinking twice about how private your connection is. A mobile browser should do […] The post What’s new in Firefox mobile: Less clutter, more control and a free built-in VPN appeared first on The Mozilla Blog.
Since February, the Firefox team has been working around the clock using frontier AI models to find and fix latent security vulnerabilities in the browser.

As part of our continued […] The post The zero-days are numbered appeared first on The Mozilla Blog.
Microsoft recently announced it’s pulling back Copilot from several of its core Windows apps — Photos, Notepad, the Snipping Tool, and Widgets. Rolling back these forced AI integrations is the right move, but this is just the most recent example of Microsoft going too far without user consent.

That’s why, today, Mozilla is announcing a strategic partnership with Mila – Quebec Artificial Intelligence Institute […] The post Mozilla and Mila announce strategic research partnership to advance open source and sovereign AI capabilities appeared first on The Mozilla Blog.
Today we’re introducing a free built-in VPN in Firefox, a new IP-protection feature designed to keep you even more private while you browse. We’re starting by offering an industry-leading 50 gigabytes of free VPN-browsing each month. Firefox has long focused on building privacy tools directly into the browser to protect you online. Over the years, […] The post A free VPN you can trust, now built into Firefox appeared first on The Mozilla Blog.
Much of what we do on the web involves looking at more than one thing at a time – booking tickets while checking your calendar, taking notes as you go through a report, or comparing options before making a purchase. The web is inherently multidimensional. For years, browsing this way meant bouncing back and forth […] The post Split View in Firefox: Two tabs side by side, right where you need them appeared first on The Mozilla Blog.

The web shouldn’t feel like it’s working against you. Yet so much of it now is designed to pull you off course: endless feeds, pop-up windows and content that looks credible until it isn’t.

Firefox is here to help you navigate the […] The post Meet Kit, your companion for a new internet era appeared first on The Mozilla Blog.

The unique architecture of the web enables a much higher degree of user privacy than exists on other platforms. Many factors contribute to this, but an essential one is that you don’t need to log in to start browsing. Sharing details about yourself with a website is an optional step you can take when you […] The post The web should remain anonymous by default appeared first on The Mozilla Blog.
For more than two decades, Firefox has been 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. A few weeks ago, Anthropic’s Frontier Red Team approached us with results from a new AI-assisted vulnerability-detection method that surfaced more […] The post Hardening Firefox with Anthropic’s Red Team appeared first on The Mozilla Blog.

AI is changing the web, and people want very different things from it. We’ve heard from many who want nothing to do with AI. We’ve also heard from others who want AI tools that are genuinely useful.

We’re at a fork in the road. AI is here, and has started to define how we search, create, communicate — and how the web itself works.

Mozilla has always believed that technology should empower people. That belief shaped the early web, when browsers were still new and the idea of an open internet felt fragile. Today, the technology is more powerful, more complex, and more opaque, but the responsibility is the same. The question isn’t whether technology can do more. It’s […] The post How Mozilla builds now appeared first on The Mozilla Blog.

The future of intelligence is being set right now, and the path we’re on leads somewhere I don’t want to go.

In that world, […] The post Owners, not renters: Mozilla’s open source AI strategy appeared first on The Mozilla Blog.
