I'm a big fan of WaterFox! I switched when Firefox decided to add a ton of AI crap without providing a "turn this crap off" button (you could force it, but I don't want to fight my tools). Really good experience, been recommending it to all my friends.

Librewolf is also good, and I use that on one of my other machines. I like Waterfox a bit more, but that's probably just personal taste. Both are solid and both cut the mold off the tasty cheese that is Firefox

For what it is worth they have now added a global kill switch for AI features. Though I appreciate the local translation feature so I'm inclined to keep it on just for that.

I've been using Waterfox on deskop for years and adore it. Firefox for mobile does great. I don't grasp how anyone uses Chrome as their daily driver willingly aside from just inertia.
