In descending order of good privacy:
- Tor (not necessary for the majority of use-cases)
- Hardened Firefox (you can find tutorials for this with a quick Google)
- Mullvad
- Librewolf
- Brave (yes there's controversy about crypto and the founder being a dick, it's still miles better than Chrome)
- Everything else
- Chrome itself (seriously, don't use Chrome)
My number 1 recommended plugin for privacy and getting rid of ads is always ✨ uBlock Origin ✨ (not uBlock, that's not the one by the OG dev).
