AI isn't necessery, it's a hindrance.
I switched to Firefox on all devices for its better performance and better privacy, and of course it not having a gross amount of AI shoved into it. I work very well with this browser without AI, adding more of it will simply ruin the experience completely. Many people use Firefox because they wish to avoid AI from the start, Firefox shines thanks to this and should openly express how it won't fall into the same trap. Don't let this become every other browser.
