I came across a Tumblr post detailing how to disable AI “features” in Firefox as of 11/20/25 and I’m expecting an arms race of new/changed fields vs new strategies to disable them. So I wanted to ask, what would you recommend a lifelong Firefox user use, for PC and Android?


The Tumblr post:
The fields:
browser.ml.enable browser.ml.chat.enabled browser.ml.chat.menu browser.ml.chat.page browser.ml.chat.page.footerBadge browser.ml.chat.page.menuBadge browser.ml.linkPreview.enabled browser.ml.pageAssist.enabled browser.tabs.groups.smart.enabled browser.tabs.groups.smart.userEnabled extensions.ml.enabled browser.search.visualSearch.featureGate
If you add three back ticks (```) to the beginning and end of the list, it will format as a code block instead of a bunch of links
Interesting that I had a lot of these already set to False and I definitely haven’t gone through this process before. Maybe there was a prompt somewhere that I said no to?
Appreciate the list though just to be extra sure!
Half of them were already False for me. I think I remember right clicking and seeing an AI option that I said no to. That probably disabled some of the features listed.
