Firefox(Librewolf) is not as secure as Chromium, and none of them are effective against fingerprinting.
A little different thing I do for number 2:
Compartmentalize your browsers (and they're Firefox forks), harden them using this guide:

Use a different browser for a different purpose (for example, I'm using LibreWolf, hardened to the nines, for #nostr and Mastadon).
Discussion
Nope. If you want fingerprints wiped going to have to harden
Chromuim is dominating the internet, and has DRM, not to mention you can't do what Firefox does with MV3, since Google added in arbitrary rule limits for ad blockers.
It's not protecting you against many spying attacks. Learning how to secure Firefox should be required for all privacy advocates who love to use Firefox forks specifically for compartmentalization.
