Librewolf if you want something more heavy handed with the privacy. It can break some websites though if you don’t tune it. Firefox for an every-man browser that isn’t chromium based. I personally run Firefox with ublock because I’m not looking to use Google stuff anymore. I’m waiting to see Orion’s deployment on Windows and Linux. I’ve been using that on my iPad and phone and like its potential.

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)

Optional but recommended tip: Check out Celenity and his guides. You can also check out his Recommendations for services you use

I use Zen as my daily driver, and Firefox on mobile. I isolate different areas of my life with containers and profiles but you don’t necessarily need to do all that. It’s good and private out of the box

firefox on everything. it supports ublock origin on mobile too, it's great.

Pick either chrome or Firefox. I use Firefox when possible. Configure it to delete all cache, history and cookies when closed. Install the appropriate container extension. Install ublock origin and privacy badger. Install your password manager of choice. Configure dot or doh perhaps using the socks proxy settings.

Use containers to avoid sharing cookies. Close your browser when you’re done using it. If you are going to walk away from it you’re done using it, close your browser.

If you’re worried about remembering your tabs, bookmark em. You can’t rely on ctrl-shift-t

If you’re worried about fingerprinting, use a window size that reflects a common screen size or common device.

Browsers//

Android: Ironfox (BEST OF ALL) and Cromite Linux: Librewolf, Zen, and Ungoogled Chromium Anything Apple: Orion Windows: Anything from Linux section

For future reference keep an eye on Servo, and I guess Ladybird too

Recommend all that!

Librewolf potentially? You don’t need to use multiple browsers if you can contain them to profiles, this could be a good set up for you potentially.

I'm using Waterfox: privacy respecting and AI-free fork of Firefox.

LibreWolf is a Firefox fork hardened for privacy. I suggest to disable the cookie and history deletion for it to be more usable. It has a more tradicional UI than Zen.

Vivaldi is chromium... It's also not FOSS. As with most the other people in the comments, I'd suggest Librewolf, though I'm looking into going back to regular Firefox with a custom user.js for added security.

I would use Mullvad Browser for browsing as it has very strong anti-fingerprinting/tracking and Brave/Librewolf (or a different privacy Firefox fork) for anything that you need to be logged in for.

Falkon is pretty decent if you're using kde plasma.

Zen is Firefox but really pretty and with a ton of added functionality and customization.
