Until they pulled this recent spying stuff I was a firefox user, but now I'm testing librewolf, zen browser, and brave. I might give Basilisk a try too. I'm also keeping an eye on ladybird but it looks like it isn't really ready yet.
Ultimately on the desktop I'll need something based on firefox because it can be hardened better than anything else I've seen and my work has me regularly dealing with some nasty websites.
I still have to find some options for mobile though.
Well, I wish you luck then. I still don't think PPA represents capitulation to advertisers in any significant sense, but I can understand why a purist would disagree, and certainly the fact that they get so much of their money from Google makes me fear that the extent to which they constitute a real alternative may dwindle or disappear someday.
