I don't want AI in my browser. I've been a consistent Firefox user for years but this might make me switch to a fork.

Under about:config, browser.tabs.groups.smart you can disable it.

....for now.

That is the standard playbook:

  • Introduce unpopular feature
  • Defend it by saying there is an option in preferences to disable it
  • Later hide the option in some obscure config instead
  • Finally, remove the option to disable it

Thanks for reminding me to do this.

I don't really want to have to keep checking the release notes for new AI bullshit, though.

There's an option labeled Use AI to suggest tabs and a name for tab groups.

On 141 it's listed in Settings under the General => Tabs section.

It changes browser.tabs.groups.smart.userEnabled.

Looking at it further, either option will disable it. Here's the code that checks both values, https://github.com/mozilla-firefox/firefox/blob/FIREFOX-ANDROID_141_0_3_RELEASE/browser/components/tabbrowser/content/tabgroup-menu.js#L481

there used to be a more accessible toggle in settings for that. why tf would they take that out?

[-] Oisteink@feddit.nl 9 points 1 day ago

To keep most users from disabling it. Just like why the don’t make it opt in.

Also everything that starts with "browser.ml.chat".
