How to disable AI models in Firefox

Firefox recently rolled out a new update that includes on-device AI, displaying local AI models that power features like tab groups and link previews. While the AI ​​feature is handy, not everyone wants to use it on the Firefox browser, as many are concerned about the privacy implications of the browser. Here's how to disable the AI ​​model in Firefox.

 

How to disable AI models in Firefox

Step 1:

First, you need to update your browser to the latest version Firefox 140. Launch Firefox Nightly on your computer, then click Menu > Add-ons and Themes . Then you find the On-Device AI section in the Add-ons Manager.

Step 2:

You will now see a list of AI models in your Firefox browser . Each model includes its file size, model version, and last updated date.

 

Step 3:

To delete AI models on the browser , click on the 3-dot icon on the model you want to delete and select Remove in the displayed list.

After disabling AI image modeling in Firefox, you will see some changes:

• Features like Smart Tab Grouping or Link Preview will stop suggesting AI-powered groups.
• The browser may run faster on some older devices.
• No data is deleted from the computer and users have better control over privacy.
• If you re-enable these features, the models are automatically reloaded.
