Starting with the 2026/27 season, Firefox is Wrexham AFC’s official web browser partner and front-of-kit sponsor on the men’s and women’s teams.

Web Serial in Firefox 151 helps makers connect, code and control Adafruit hardware projects directly in the browser.

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 to advance open source and sovereign AI capabilities.

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.

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.

Don’t remember why you have all those webpages open? Now you can leave yourself a note for any tab.

Anthropic’s team got in touch with Firefox engineers after using Claude to identify security bugs in our JavaScript engine. Critically, their bug reports included minimal test cases that allowed our security team to quickly verify and reproduce each issue.

In my view, this is the exact right approach. LLMs aren’t going anywhere, these tools are here to stay. The only question is how they will be developed going forward, and who controls them. Boycotting AI is a really naive idea that’s just a way for people to signal group membership.

Mozilla is pleased to announce that Amy Keating has joined Mozilla as Chief Business Officer (CBO).

Mozilla has always believed that technology should serve people — not the other way around. As we enter a moment of rapid change in how people experience the internet and AI, we’re focused on building products that are private, transparent, and put people in control. Today, we’re excited to take an important step forward in that work by welcoming John Solomon as Mozilla’s new Chief Marketing Officer.

Sound like more AI bullshit in Firefox, but privacy, because Mozilla is “trusted”.

Especially as demand for video grew, the web needed a next-generation codec to make high-quality streaming faster and more reliable. H.265 promised efficiency gains, but there was no guarantee of another OpenH.264-style arrangement. The risk was another fragmented ecosystem where browsers like Firefox couldn’t play large portions of the web’s video.

Whenever you open Firefox, we want it to feel like it speaks your language and matches your style. This month, our mobile team is rolling out features inspired by community ideas, user requests and the small everyday moments that make browsing more delightful.

In 2025, we rolled out one update after another, all aimed at making your browsing better — with more flow, speed, choice, and control over your information and experience. Your window to the internet, whether on desktop, mobile, or across all your devices, has gotten an upgrade this year.

Last year, the Firefox team set out to test something fans requested: choosing a custom app icon. The experiment was simple. Offer a small set of options and see how people use them.

It’s not every day a video codec wins an Emmy. But yesterday, the Television Academy honored the AV1 specification with a Technology & Engineering Emmy Award, recognizing its impact on how the world delivers video content.

Last month, Firefox turned 21, marking two decades of building a web that reflects creativity, independence and trust. At TwitchCon, we celebrated by launching billionaires into space and launching a new card game, Data War.

AI isn’t just another tech trend — it’s at the heart of most apps, tools and technology we use today.

Tab groups have become one of Firefox’s most loved ways to stay organized — over 18 million people have used the feature since it launched earlier this year. Since then, we’ve been listening closely to feedback from the Mozilla Connect community to make this long-awaited feature even more helpful.

We recently shared how we are approaching AI in Firefox — with user choice and openness as our guiding principles. That’s because we believe AI should be built like the internet — open, accessible, and driven by choice — so that users and the developers helping to build it can use it as they wish, help shape it and truly benefit from it.

Now, we’re excited to invite you to help shape the work on our next innovation: an AI Window. It’s a new, intelligent and user-controlled space we’re building in Firefox that lets you chat with an AI assistant and get help while you browse, all on your terms. Completely opt-in, you have full control, and if you try it and find it’s not for you, you can choose to switch it off.

Today, Mozilla is thrilled to join the Digital Public Goods Alliance (DPGA) as its newest member. The DPGA is a UN-backed initiative that seeks to advance open technologies and ensure that technology is put to use in the public interest and serves everyone, everywhere — like Mozilla’s Common Voice, which has been recognized as a Digital Public Good (DPG). This announcement comes on the heels of a big year of digital policy-making globally, where Mozilla has been at the forefront in advocating for open source AI across Europe, North America and the UK.

With Firefox 145, we’re rolling out major privacy upgrades that take on browser fingerprinting — a pervasive and hidden tracking technique that lets websites identify you even when cookies are blocked or you’re in private browsing. These protections build on Mozilla’s long-term goal of building a healthier, transparent and privacy-preserving web ecosystem.

Increasingly, businesses, schools, and government institutions deploy Firefox at scale for security, resilience, and data sovereignty. Organizations have fine-grained administrative and orchestration control of the browser’s behavior using policies with Firefox and the Extended Support Release (ESR). Today, we’re opening early access to Firefox Support for Organizations, a new program that begins operation in January 2026.

What would your browser history say about you? Whether you were getting things done this week or just collecting tabs, a new Firefox extension helps you reflect on your digital habits.

Advertising can and should work better — for people, for publishers, and for brands. That belief is what drives Mozilla’s growing investment in rebuilding digital advertising around trust, transparency and fairness.

An ads milestone in marketing reach without data risk. The ad industry is shifting, and with it comes a clear need for advertisers to use data responsibly

We’re celebrating Firefox’s 21st anniversary this November, marking more than two decades of building a web that reflects creativity, independence and trust. While other major browsers are backed by billionaires, Firefox exists to ensure that the internet works for you — not for those cashing in on your data.

Today Mozilla is excited to announce Raffi Krikorian — technologist, innovator and community builder — as our first-ever portfolio wide Chief Technolog
