No. There is a lot more than that. The AI stuff appears in places in the UI where other things used to, like in right-click menus and when you are entering text into fields. And it's not opt-in. It's on by default. Unless you are willing to search for how to turn it off and open the non-GUI about:config stuff and modify raw settings in a text table (with no descriptions or help text next to them) then you can't even turn it off. Also, the AI stuff takes up disk space.
There's not really though. The most annoying thing was when highlighting text a weird icon showed up. I clicked on it, and one of the most prominent buttons on it was "turn this shit off". So I did.
This will probably be a bit useful for me when I want to copy web pages into Gemini for data extraction.
