I only run Firefox on every computer and phone that I own. I'm extremely satisfied with its performance so far and sincerely hope they keep improving. My second alternative is Brave, just in case I can't use Firefox. My very last choice is Chromium. On Firefox I highly recommend these plugins:

AdNauseam: https://addons.mozilla.org/en-US/firefox/addon/adnauseam/

Consent-O-Matic: https://addons.mozilla.org/en-US/firefox/addon/consent-o-mat...

Firefox Multi-Account containers: https://addons.mozilla.org/en-US/firefox/addon/multi-account...

I don't care about cookies: https://addons.mozilla.org/en-US/firefox/addon/i-dont-care-a...

Edit: As mentioned below, avoid Consent-O-Matic unless you trust Avast.
