On Linux Desktop, I generally use Librewolf (although I also use Vanilla Firefox and Ungoogled Chromium depending on the use case). I do also modify Librewolf a bit further in about:config, and have styled it to be much more minimal using userChrome.css.
Some of my favorite Extensions include:
I have others, but these are the ones that have been game changers. I also browse using DuckDuckGo Lite which cuts back on the distractions and loads fast. The use of DuckDuckGo Bangs also allows for very fast browsing and getting the info I need quickly.
On my Android phone, I use the Mull, Vanadium, and Vanilla Chromium browsers for various use cases, with Mull being the go to. There are a more limited set of extensions on Mull, but have managed to get it very similar, using uBlock, NoScript, DarkReader, DDG Lite, and have used this filter list with ublock to get pretty much the same effect as ByPass Paywalls.
Obviously, I generally have a very different experience browsing the web than most, and generally am not bombarded by ads as I also use Invidious, NewPipe, SponsorBlock, and yt-dlp (which has a sponsorblock flag btw) to grab any vids/music I want. Hope these resources help someone out.
