Key Highlights

• Firefox 148 launches AI controls on February 24, 2026.
• Users can block all AI tools or enable selected ones.
• Features include translations, alt text in PDFs, tab grouping, link previews, and chatbot integration.
• Settings persist across browser updates and can be changed anytime.

Mozilla is bringing a new AI controls section to Firefox, starting with version 148 on February 24, 2026. This update gives users a single place to block current and future AI enhancements — or fine-tune which ones they use.

The change matters because AI is becoming a bigger part of the web, but not everyone wants it. Some want full automation; others want none. Mozilla’s answer: give users total control over AI in their browser.

What Can You Control?

The AI controls panel in Firefox’s settings will let you manage these features individually:

• Translations – browse in your preferred language.
• Alt text in PDFs – image descriptions for accessibility.
• AI-enhanced tab grouping – suggests related tabs and group names.
• Link previews – see key points before clicking a link.
• AI chatbot in the sidebar – integrate services like ChatGPT, Anthropic Claude, Microsoft Copilot, Google Gemini, and Le Chat Mistral.

If you want none of them, the Block AI enhancements toggle turns them all off.

Why It Matters for Privacy and Preference

When this toggle is on, users won’t get pop-ups or reminders about AI tools. Preferences remain locked across browser updates, but they can be changed any time. This ensures that whether you’re pro-AI or want AI-free browsing, Firefox respects your choice.

Early Access in Firefox Nightly

Those who want to try AI controls early can opt for Firefox Nightly. Mozilla is collecting feedback on its Mozilla Connect platform before the wider rollout.

The Bottom Line

With Firefox AI controls, Mozilla is putting browsing choices in the user’s hands. Whether you block every enhancement or pick specific tools, you decide how AI interacts with your web experience — and that decision sticks.
