Based on the answers to this StackOverflow question and this blog post, here are the 16 (!!!) AI-related settings in new versions of Firefox that you'll want to disable/set to false, and that might be turned back on with each update:

- browser.aiwindow.enabled
- browser.ml.chat.enabled
- browser.ml.chat.menu
- browser.ml.chat.page.footerBadge
- browser.ml.chat.page.menuBadge
- browser.ml.chat.page
- browser.ml.chat.shortcuts
- browser.ml.chat.sidebar
- browser.ml.enable
- browser.ml.linkPreview.enabled
- browser.ml.pageAssist.enabled
- browser.ml.smartAssist.enabled
- browser.tabs.groups.smart.enabled
- browser.tabs.groups.smart.userEnabled
- extensions.ml.enabled
- sidebar.notification.badge.aichat 

Enter "about:config" in the browser bar and then search for each of these and disable them, turn them off, or set them to false as appropriate.

Depending on which version of Firefox you have you may not have all these configuration options.

Check your smartphone browsers too!
