Firefox on desktop and Mobile. To keep browser monopoly away. All settings set to max strictness except no DNS, because I have a VPN. Firefox works on 99.9% of sites. You can use a script called Arkenfox, to harden FF even more, almost to Librewolf, but with the advantage of updates coming directly from mozilla. I love the sync function across FF, so that's why I have it on my mobile as well, it's seemless.

On my laptop, Brave for non-"personal" things (such as fediverse, SoundCloud, AI tools, daily browsing, etc) and Firefox for "personal" things (such as WhatsApp Web, LinkedIn, accessing local govt. services, etc). On my smartphone, Firefox for everything (I disabled the native Chrome).

I've been using Brave in a daily basis because it's well integrated with adblocking tools, especially considering the ongoing strife regarding Chromium's Manifest V2 support, where Brave nicely stands keeping its Manifest V2 support independently of what Google wishes or not.

Firefox is also good, but I noticed that, for me, it has been slightly heavier than Brave. So I use it parallel to Brave, for things I don't need to use often. For mobile, it's awesome, as it is one of the few browsers that support extensions, so I use Firefox for Android, together with adblocking extensions.

Tor Browser

Firefox with plugins. If we want there to be anything but Chromium and Safari in the future it's simply what needs to be done. Forks of Firefox will disappear when Firefox does ...

Currently using Firefox but I'm also keeping an eye on Ladybird.

i use hardened firefox but i also use vivaldi when i need to use chromium for whatever reason

Depends on which computer I'm using. Netscape 4 still works relatively well, as long as you're selective about which sites you try to access.

A combination of Zen-browser, Firefox and Librewolf.

waterfox

On mobile the only choice is Mull. And on desktop even you could use Arkenfox, but recommended to you to use the Mullvad brower

Firefox (well, librewolf, but forks are a matter of personal preference).

Chrome (Ungoogled chromium) is used as a fallback for the occasional site that doesn't work with my restrictive FF configuration.

Both have uBlock, though they're configured differently to suit their individual purposes.

Firefox on mobile, desktop and iPad.

Zen Browser on pc, and Fulguris on android.

PC - Firefox with ublock, multi container extension Android - Mull with ublock extension, i delete data on exit

Mostly LibreWolf, but I’ve been enjoying Zen Browser recently. It’s based on Firefox but with lots of cool extra functionality baked in. It is still in alpha though and I’ve experienced some bugs, including it crashing my whole system a couple of times, but it’s very promising

librewolf on my laptop, firefox with ublock origin at work and on mobile

Use more than one.

On PC, my daily driver is Firefox Developer, patched with my CSS along with Betterfox for enhanced privacy over ArkenFox. I am an Admin and run a number of sites, so this helps.

Librewolf as general backup. Mullvad as second backup but I find that I am not the best use case for it, on top that I use different VPN services. It is for non-tech users, is not bad, just not the best tool for me but it is what I will tell people to use when using my PC since the other two have very UI minimal, heavy keyboard-centric setups. Tor for when I need more privacy/testing. Keep a copy of ungoogled Chromiu, mostly vanilla, only uBlock, again for testing and the off-chance fuzzy site but barely ever use it. They all, aside UG, sync bookmarks via Nextcloud instance so I do not need to sign into FF sync.

On Android, Mull, or CookieWeb Preview because the excellent extension management due to their pop-up window. Great for things like uBlock on medium mode, otherwise medium mode on mobile is a pajn to use, on Mull I keep it on Easy mode. Nevertheless, uBlock is a must in today's internet. Tor for when travelling abroad and do not need to sign-on to anything. Keeping extensions to a minimum. Each browser connects to different DNS services to minimise overlap, along rotating VPN servers from non-5 eyes countries as the minimum. Sounds like a lot but once you set it up, it is mostly set-and-forget.

On Mobile I use Firefox Nightly but it is a pain. It crashes all the god damn time. I don't know how y'all do it, Mull is the same thing because of the upstream. I sometimes consider using Vanadium but I ain't pissed enough yet, I think.

On Desktop, Librewolf for mostly everything that I can manage work with it, what doesn't I open whatever other browser that's available.

A customized copy of ungoogled chromium

Floorp

Since I have not seen it yet in the comments, I use Floorp, a Firefox fork with some nice UI improvements (and apparently some performance improvements, but both are very fast for me).

Desktop, Librewolf

Mobile Brave, Mull

Librewolf on my personal laptop.

Tor Browser on both Linux/Gnome and Android. I believe I get not only the benefits of ad-blocking and anti-tracking measures but also IP-obfuscation through the Tor network. Sure, there are sites that won't serve content to the Tor network, but screw them!

firefox but hardened. dont want to use any chromiumed browser bc of the monopoly, and librewolf is just a fork of firefox so too little difference to switch

Since you're using Edge, I'll assume you're running Windows. In that case, I'd recommend either Librewolf or ungoogled-chromium.

I, myself, use Mullvad Browser and Links2, but they're not quite as good for new users.
