One point about waterfox,it s a heated debate in the community i guess. Waterfox apparent.y isn’t updated as quickly as FF? Some claim it is a security risk, others claim its not that big a deal?
I don’t know much about it so can’t comment beyond pointing that out. Perhaps it sjust fine, but i can attest that it works really well
From what I understand it is at least unhooked from Mozilla and in competition with them. So both of those are a plus in my book. And alone it might not be as safe as Brave, but... Add NoScript and Ghostery to it and it is even more secure that Brave. They stop EVERYTHING by default. You have to turn things on sometimes to see them, but only what you need to use the site and the other 50 hidden scripts remain blocked.
