How to turn off AI features in Firefox and Chrome
Firefox now has a single switch. Chrome has a handful of toggles and no master off. Where each setting lives, and what it leaves alone.
To turn off AI features in a browser you have to use that browser's own settings, and Firefox and Chrome work very differently. Firefox now ships one switch. Chrome spreads the controls over several toggles. The steps below come from Mozilla's and Google's own help pages as read on October 10, 2026. Menu labels change between versions and some features roll out gradually, so use the settings search box if a label differs on your screen.
Firefox: one switch for everything
Mozilla added an AI Controls page to Firefox Settings in early 2026, as its support article and announcement describe. It is in the desktop version of Firefox; update first if you don't see it.
- Open Firefox Settings (labelled Preferences in some versions).
- Choose AI Controls in the left column.
- Turn on Block AI enhancements.
Mozilla says this hides new and current AI features and the pop-ups that promote them, and that future features stay blocked while the switch is on. The announcement, dated February 24, 2026, lists website translations, image descriptions in PDFs, AI-enhanced tab groups, link previews and a chatbot in the sidebar among the features the panel controls.
To keep one feature, open its dropdown and choose Available (you can see and use it) or Enabled (you have opted in). Blocked hides it, and for on-device AI the models already downloaded are removed.
What it doesn't cover: Mozilla's support article says extensions can still use third-party AI services on their own. The panel lists Firefox's own features, and the AI answers a search engine or a website writes are not among them. Firefox for Android and iOS have their own AI Controls screens.
Chrome: several toggles, no master switch
Google documents Chrome's AI controls in separate help pages, and none of them describes one setting that removes everything. Start at Settings and then AI innovations.
Hide Gemini in Chrome
Under AI innovations choose Gemini in Chrome. In Preferences, turn off Show Gemini at the top of the browser, and the keyboard-shortcut option for your system: Show Gemini in Mac menu bar and turn on keyboard shortcut on a Mac, or Show Gemini in system tray and turn on keyboard shortcut on Windows. You can also right-click the top of the browser and choose Unpin Gemini. Google's help page describes hiding the icon and shortcuts, and says an organization's administrator can disable Gemini in Chrome. It does not describe a user setting that removes it entirely.
Stop tab sharing
On the same page, under Permissions, turn off Share current tab by default. By default, content from your current tab is shared so Gemini can answer questions about it. The same section has a Let Gemini browse for you toggle.
Remove the on-device models
Under AI innovations there is a separate On-device AI toggle. Per Google's help page, turning it off makes Chrome delete the on-device generative AI model files, stops features that need them, and stops Chrome downloading them again while the setting is off. Google lists help with writing, scam warnings, page summaries and tab organization as features that use these models, and notes that some Chrome AI features don't use them and may keep running.
Edge: look for Copilot and AI
We did not find a Microsoft help page that documents one switch. In a Microsoft Q&A thread, an independent advisor says Edge's related options can be turned off in Settings under Copilot and AI, and that Bing has no option to turn off Copilot answers in its search results. That is a community answer, and the menu names move between versions, so search Edge's settings for "Copilot". We left Safari out because we could not confirm the steps in Apple's own documentation.
What turning off browser AI doesn't change
These settings control what your browser's maker adds: sidebars, summaries, assistants, tab helpers. They do not change which websites show up in a search. Many of those results are pages built by AI site generators or mass-produced for traffic, and no browser setting above touches them. The two problems are different, as the guide to what a no-AI web browser is explains.
We make Kitsuvo, which belongs to the second group: it filters likely AI-built websites out of Google, Bing and DuckDuckGo results and shows the evidence for each score. Kitsuvo asks you to use a different browser, so the two approaches stack rather than replace each other: use Firefox's switch or Chrome's toggles for the browser's own AI, and a results filter for the web. Kitsuvo's rule-based checks need no account, and its AI explanations are optional services you connect yourself.

Questions people ask
Can you completely disable Gemini in Chrome?
Google's help page describes hiding the Gemini icon and shortcuts and turning off tab sharing, and it says an administrator can disable Gemini in Chrome. It does not describe a user setting that removes it entirely.
Does Firefox's Block AI enhancements switch stop AI in search results?
No. The AI Controls panel covers Firefox's own AI features, such as translations, PDF image descriptions, tab-group suggestions, link previews and the sidebar chatbot. A search engine's AI answers are not on that list, and Mozilla's support article says extensions can still use third-party AI services.
What happens when you turn off On-device AI in Chrome?
Chrome deletes the on-device generative AI model files and stops features that depend on them. It does not download them again while the setting is off. Some Chrome AI features do not use these models and may keep running.
