Firefox Will Soon Let You Turn Off All Generative AI Features

Mozilla is taking a clear stance for users who don’t want artificial intelligence baked into their browser. Starting later this month, Firefox will introduce new controls that allow people to block all generative AI features—or pick and choose which ones they want to keep.

Beginning with Firefox version 148, rolling out on February 24, desktop users will see a new AI Controls section in browser settings. From there, anyone who prefers a no-AI experience can enable a single toggle labeled “Block AI enhancements.” Turning it on will remove access to current and future AI tools, along with any prompts or reminders encouraging their use.

For users who are more selective, Firefox will also offer granular controls. Individual AI features can be turned on or off, including built-in translations, AI-generated alt text in PDFs, AI-assisted tab grouping, link previews, and the browser’s sidebar chatbot. The chatbot supports several third-party services, such as ChatGPT, Anthropic’s Claude, Microsoft Copilot, Google Gemini, and Le Chat Mistral.

Mozilla says the update reflects a wide range of user preferences. In a blog post, the company explained that while some people want nothing to do with AI, others find certain tools genuinely helpful. Giving users control, Mozilla says, was the most consistent response to that feedback.

The announcement follows the appointment of Anthony Enzor-DeMeo as Mozilla’s CEO in December. At the time, Enzor-DeMeo said Mozilla would continue investing in AI features—but emphasized they should always be optional and transparent.

“AI should always be a choice,” he wrote. “People should understand why a feature exists and what value it provides.”

Mozilla’s move comes as competition in the browser market heats up. Once dominated by Firefox and Google Chrome, the space is now seeing pressure from newer players like Arc, Perplexity, OpenAI, and Opera, many of which are heavily focused on AI-driven experiences.

Even as it expands its AI efforts, Mozilla says transparency remains a priority. According to CNBC, Mozilla President Mark Surman recently described his goal as building a “rebel alliance” of startups, developers, and public-interest technologists focused on making AI more trustworthy and limiting the unchecked power of major AI companies.

Mozilla reportedly plans to deploy around $1.4 billion in reserves to support tech companies and nonprofits aligned with those goals, backing projects that promote AI accountability and transparency as the technology continues to grow at a rapid pace.
