These are all valid reasons. I’ll also add that I personally desire manual control over my computing experience. A huge part of the reason I run Linux is that it does exactly what I tell it to and nothing more. When you start introducing other agents to my user agent, it ceases to be a user agent. Something else is arranging my tabs. Something is popping info up into in my face that I didn’t ask to see (and which might be incorrect). I just want these things to go away so my browser can be my browser again and not be under the control of a random word guesser.

Yes, I have turned these features off, but I don’t even want them installed. They’ve been force-installed onto my system through software that didn’t used to do that. If I lose my config, I have to go turn it all back off again. I’d rather just not have the feature anywhere in the software. I’d rather Firefox just not smuggle AI features onto my PC at all.
