If you want a privacy-focused Chromium browser with no Google stuff and also one that has extensions then, check out Cromite.

If you want a privacy focused browser which runs the most smoothly out of all privacy focused browsers and is the best one for simple people, I suggest Brave. (sadly it's a US product)

And there's always the Firefox forks, I would recommend these: Iceraven Browser, Fennec, WebLibre, IronFox. I would suggest IronFox and the most here since it's the best one for privacy and doesn't need any more hardening since it's mostly fully hardened out-of-the-box. This is specifically for Android. If on desktop, you can check out LibreWolf, Mullvad Browser, Zen Browser etc. I recommend LibreWolf the most here.

Main advice: Every browser has pros and cons. You have to use each one and figure out the best browser for yourself. For example, Brave is greatly hardened out-of-the-box and every site runs very smoothly. So, great convenience. But sadly, it's a US product! Cromite has no Google stuff and runs smoothly too, but it's not hardened out-of-the-box. You have to manually add filter lists to improve your experience. IronFox is greatly hardened out-of-the-box, but it's sometimes too hardened that sites break or behave weirdly. And sites also don't run as smoothly as it runs on Chromium browsers (this happens for any Firefox browser at all, especially on Android)
