Flyingfluffypiglet: Brave is quite well ranked in terms of privacy/security, Firefox too since you can pretty much lock it down, Chrome of course in an epic fail in that but that's not really surprising. Tor is one also but caution as their exit nodes are notorious for IP leaks. And because entry nodes do see your IP anyway, that's one browser best to use in conjunction with VPN that offers TOR over VPN settings. Any compromised Tor entry/exit nodes are bad news for the user.
Spectre: Apart from auto tampering with your browser such as the robots firefox incident or brave deciding to autoblock old versions.
I wasn’t aware of the firefox incident. It does however highlight how little we as users, have control over our own tech.
I have to now, with anything installed, go through endless settings and setup items. For instance, Firefox has everything turned, remove all history/cookies on exit, no extensions, no themes etc. I don’t often use the private window however, not really sure what that adds to the mix. However I still have no faith in that. I suppose there is now a deep inbred distrust of anything going out of the cable from the house, I certainly wouldn’t have these things like Alexa around!
Looks like, from what I have read, Firefox is best for day to day or Brave. With tor browser as most secure and slowest.
Might also invest some time looking into vpn, either the epic browser above, or protonvpn.
