Mozilla Adds AI Window To Firefox, Letting Users Pick Their AI Model

Mozilla is taking its next big step into the AI world-this time directly inside Firefox. The company has announced AI Window, a new browsing mode designed to bring an AI assistant into your daily browsing without locking you into any single ecosystem. And in typical Mozilla style, it’s completely optional and built with user control at the centre. Also Read: Don’t Ignore This Update: Google Chrome and Mozilla Firefox Fix High-Risk Security Bugs

Think of AI Window as a separate browsing space inside Firefox, much like how you currently switch between private and regular windows. But this new mode comes with an AI assistant built right into the interface-one that can help summarize pages, answer questions, or guide your browsing. Also Read: iOS 26 Magic?

Mozilla describes it as an “intelligent and user-controlled space,” not another chat box you get stuck in. That’s the key difference. Instead of pushing users into endless AI conversations, the company wants AI to assist you and then get out of the way.

Choose Your AI Model

The good part You get to choose which AI model powers it. While Google and Microsoft push users toward their own AI systems, Firefox is going for openness, letting you pick the AI you trust. Details about which models will be supported are still under wraps, but Mozilla says the feature will be built transparently with user feedback.

Mozilla is taking a very public approach to this rollout. Development is happening out in the open, and users can join a waitlist to test the feature early.

This is not Mozilla’s first AI experiment. Last year, Firefox introduced a “shake to summarize” tool on iPhone that pulled quick summaries of web pages. But AI Window is a much bigger move-one that clearly signals Mozilla’s intent to stay relevant in an AI-powered browser market that’s suddenly getting crowded.

In a blog post announcing the feature, Mozilla wrote, “While others are building AI experiences that keep you locked in a conversational loop, we see a different path – one where AI serves as a trusted companion, enhancing your browsing experience and guiding you outward to the broader web.”

What Comes Next?

AI Window isn’t live yet, but it’s already generating curiosity. Firefox says it will share more details soon, and early testers will help shape the experience.

Whether this helps Firefox regain some ground in the browser market remains to be seen. But one thing’s clear: Mozilla isn’t sitting out the AI race-it’s choosing to run it differently.
