How they list "AI controls — allow, restrict or disable AI tools" which Firefox now has under Enterprise, but not normal version.
It's in the settings, under AI Control: https://celsoazevedo.com/files/2026/ff-settings.webp
You can already do that in regular firefox. I think in this case, it's adding the capability to enable/disable via policy at the enterprise level.
Firefox does have a setting to disable all AI features. It's in your settings: Settings > AI Controls > Block AI Features
There is a AI menu in Firefox where you can disable individual AI features, as well as a single toggle to disable every current and future features.
