Firefox is not the devil, but "ideologies aside", the basic idea is:
-
(Just like microsoft), They could have just decided to put it in one of the "many" variant of the product, name it FoxAI, let the users decide and call a day. Instead, they've chosen to force a very heavy component like that on the main version out of blue.
-
Switched or not. Now, you'll have 'way' more bloat on a browser, who should be focused on speed and performance.
-
The whole thing about AI on free stuff is to get as much data as possible to train. You have to trust them to switch it off completely.
