How to Disable AI Models in Firefox

This updated guide explains how to disable AI models in firefox with clear steps, practical tips, and useful context. 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.

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 choose 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 , select 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.
