(Image: Mozilla)As the AI browser wars heat up, Mozilla has announced it is upgrading Firebox with a built-in assistant that will let users chat with AI as they navigate the web.The new ‘AI Window’ is an intelligent and user-controlled space where users can get help from an AI assistant as they browse on their own terms, the non-profit organisation said in a blog post on Thursday, November 13.AI Window in Firefox will not be enabled by default and users will have to opt-in to try it. They can also disable it whenever they want, Mozilla said, adding that the AI-powered upgrade is being developed as open-source.The feature is rolling out in testing to users on a waitlist. “You can continue using Firefox as you always have for the most customizable experience, or switch from classic to Private Window for the most private browsing experience. And now, with AI Window, you have the option to opt in to our most intelligent and personalised experience yet — providing you with new ways to interact with the web,” Mozilla said.Mozilla’s announcement comes at a time when tech companies are racing to build generative AI-powered browsers amid a fundamental shift in user behaviour when looking up information online. Many AI-first browsers such as Dia replace the search bar with a chatbot, while others such as Perplexity’s Comet or OpenAI’s ChatGPT Atlas are browsers that are built entirely around AI agents.Also Read | Perplexity adds new controls, built-in safeguards for Comet Assistant amid security concernsThese tech companies are rushing to build up their LLM-based browsers because it has emerged as the main gateway for both web access and AI use. In the midst of this, Mozilla has sought to stand out from the pack by relying on principles such as “transparency, accountability, and respect for user agency” to keep the web “free, open, and accessible to all”.“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,” Mozilla said.Story continues below this ad“In Firefox, you’ll never be locked into one ecosystem or have AI forced into your browsing experience. You decide when, how or whether to use it at all,” it added. In June this year, Mozilla added an option that lets users switch to Perplexity AI to make searches directly from the address bar via the unified search button.© IE Online Media Services Pvt Ltd
