I'm using Librewolf. The problem is that when cookies are deleted some sites will want to text you to "authenticate" your browser again. Your name and password alone are not enough.
It gets old doing this repeatedly. And it pisses me off that they act like they are being so secure by doing this yet they use a text instead of an authenticator app.
Covermytracks makes never Brave look better than, say Librewolf, because Brave randomizes fingerprinting info while other browsers try to thwart fingerprinting by all looking the same.
