Yeah, I feel like OP may not have actually used Fedora.. By default Fedora is probably the least similar to Windows of any major distro (this is actually one of the most commonly expressed frustrations with new users).

It is a tremendously unpleasant sounding word. It along with 'boob' make me cringe. I've no idea what Blep even means though.

Yes it does both of those things, Librewolf is just Firefox pre-configured for privacy. You could use Librewolf or you could configure firefox yourself to be equally private, Librewolf is just taking advantage of the features built into FIrefox but left optional for users.

Firefox with one or two extensions and a resonable configuration would be at or near the top of the list. This test only compares defaults which isn't so useful if you are someone that takes the time to setup your browser.

Tracking/advertising corporations have developed techniques called 'browser fingerprinting' where innocuous seeming things like screen size and the fonts you ahve installed on your system can be used to uniquely identify you and track you across the internet even without cookies or anything like that.
