The single best news I have heard from @moznews in ages:
"We hear you. We are actively working on a single, easy switch to turn off all AI features at once if that鈥檚 what feels right for you without needing to go to about:config."
I mean, I'd much rather the #Mozilla Foundati on invest their limited effort in stuff people actually WANT. But absent that, a way to turn off that stuff that no-one wants is at least Not Actively Harmful.
