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).
