I'm using Firefox 58 (Quantum), before I was using Chrome but it's Google so mehhh. And I hate Chrominium based browser because their is always Google behind.
I'm using DuckDuckGo, with addons: uBlock Origin (don't use Adblock please), Privacy Badger, LastPass (there is no good alternative with no cloud), HTTPS Everyone and Shaarli (linked with my Shaarli: https://links.kiru.space/).
