Do not try to do anti-fingerprinting yourself. Cobbling together your own configuration will only make you stand out more. Use a pre-configured browser from a reputable company. This way you blend in with everybody else using the same browser. And don't install extensions either unless you really know what you're doing. Extensions usually change your fingerprint.
Use Tor Browser for browsing over Tor, Mullvad Browser for everything else. Librewolf is fine for when you don't care about hiding your fingerprint, like when you are logging into email and bank accounts.
