I swear this question comes up everyday in Lemmy 😅.

Firefox, I just use Firefox because, it works, it has enough privacy measures, and everyone is looking at the codebase, something that cannot be said about most (if not all) forks.

Firefox with a handful of extensions, same on phone.

Last time a site "needed" chromium based a user agent switch did the miracle...

Just Firefox, I like the way it looks, and it's open source.

firefox on desktop: to keep away a browser monopoly for another day.

iceraven on mobile: more extensions.

Zen browser. Its a browser that looks like arc browser but its based on Firefox and has tracking removed. Its really nice. They also have their own theme system to change how the browser looks and acts

Librewolf is pretty good, i like having privacy features out of the box

Zen Browser, love the split view feature, and native vertical tabs !

It's a Firefox fork btw

Firefox for most things, but I keep a copy of Vivaldi installed because sometimes my firefox setup breaks capcha.

Firefox here

Zen Browser since last week. Is a Firefox fork.

LibreWolf.

Mullvad Browser when I'm on my Desktop, which is basically the Tor Browser but without the Tor network. The Mullvad Browser is instead designed to be used with a VPN.

Vanadium when I'm on my phone, which is is a hardened variant of Chromium providing enhanced privacy and security, similar to how GrapheneOS compares to AOSP.

And when I'm at work or using any other computer I try to mainly use Firefox.

Firefox because of extensions on mobile, literally the only browser capable of that

Librewolf for anything that does work, Brave for anything that works only on Chromium based, and Mullvad for all the crazy.

On Android it's Mull and Mulch.

Librewolf. whatever you end up choosing, don't install brave

firefox with no script.

Librewolf

Mull on mobile, mullvad and Firefox on desktop

Firefox with ublock origin for both desktop and mobile.

Those two programs alone block out like 75% of the annoyances and dangers of the modern internet. Near-complete removal of ads and a couple nice healthy adware and malware guards on top of that.

Add on a VPN and a few more Firefox extensions and I feel that I can browse the net anxiety-free.

Firefox then additional hardening through arkenfox.js, minimal extensions - uBlock + Bitwarden.

Edge isn't private so you have plenty of ways to improve

Hardened Firefox on my PC and Waterfox on my phone. Reason: mostly because I have been using Firefox for a long time and I want to stay away from Chromioum-based browsers (but not out of privacy concerns :) ).

Firefox with Betterfox user script. Then from there is a bunch privacy focused/oriented extensions. I also harden my DNS with custom host files from StevenBlack. I also point all my devices to NextDNS as another catch and also to standardize things as I use NextDNS to manage my kids access to the world.

I do need to create a private VPN (of my own) still so my mobile devices can be setup behind StevenBlack host entries.

If you want to stick with Chromium-based browsers, you could try Vivaldi. I am a Firefox user myself but Vivaldi is my backup browser for those rare occasions where I have issues. 95% of the browser is open source, with the remaining 5% being comprised of the closed source UI. Vivaldi has a pretty reasonable privacy policy, an inbuilt ad-blocker and is a 100% employee owned company. It supports all major operating systems and has a sync feature so you could use it as your main browser across all devices if you wanted.

Librewolf + uBlock Origin on desktop. Mull + uBlock Origin on mobile.
