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 […]

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. We wrote previously about our collaboration with Anthropic to scan Firefox with Opus 4.6, which led to fixes for 22 security-sensitive bugs in Firefox 148. As part of our continued […]

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.  Copilot was pushed onto users Over the […]

We’re launching across the developer and security community this week on Product Hunt and Hacker News.

The future of AI should belong to all of humanity, well beyond a handful of countries or companies. For that to happen, AI needs to be open, trusted, and built in ways that give people, institutions, and nations real choices. That’s why, today, Mozilla is announcing a strategic partnership with Mila – Quebec Artificial Intelligence Institute […]

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, […]

Don’t remember why you have all those webpages open? Now you can leave yourself a note for any tab. Tab Notes — our latest experimental feature in Firefox — are designed to help you remember, reflect, and pick up where you left off on the web by letting you attach a short note to a […]

The post Try Tab Notes in Firefox to leave a note on any page 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.

Firefox is for people who make their own choices online, from what stays private to the tools that help get things done. That commitment to choice shows up throughout the Firefox experience, and AI controls is just the latest example — making it possible to turn generative AI features off, on, or customize them feature […]

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. Staying focused and trusting your next click takes more effort than it should. Firefox is here to help you navigate the […]

We recently released a feature in the Firefox iOS mobile app called “Shake to Summarize”. The reception was remarkably positive, earning an honorable mention on Time Magazine’s best inventions of 2025.  For anyone unfamiliar with Shake to Summarize, it’s just what the name implies: when you’re browsing a webpage, you can shake your phone to […]

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 […]

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. Listening to our community, alongside our ongoing commitment to offer choice, led us to build AI controls. Starting […]

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.  Some of you love AI, but want it to work better for yourselves and society. Some of you hate it, and don’t want any of it.  We get it.  […]

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 […]
