I use Firefox on all platforms.

Librewolf

Firefox

Firefox. I'm not happy with how Mozilla Corp is operating, but I'm not switching to a Firefox fork unless there's actual developer exodus (akin to what happened to OpenOffice/LibreOffice). Ultimately, at this stage, those forks depend on upstream Firefox developers for 99% of the work.

Ironfox on smartphone, Librewolf on desktop

Netscape navigator.

Firefox, begrudgingly.

It's the best browser from a performance standpoint, and has the features i want, but it's still a bit of a resource hog. It's just that everything else is worse (slower, lacking essential features, or most often both).

Firefox, Firefox developer edition, Firefox focus, waterfox, Fennec, and Tor

I use many, usually Firefox.

I mainly use Firefox as it's the best non-chromium browser I'm aware of for both Linux and android. But I also have Vivaldi installed on Linux for the rare cases where something doesn't work in Firefox, Waterfox on some of my older android devices because Firefox no longer supports the versions of android they run, and I also have F-Droid's Fennec on one of my phones because it used to be my primary browser on android and I just never got around to switching to Firefox on that phone.

For anyone wondering why I stopped using F-Droid's Fennec, it's just because at some point (possibly a few years ago) they announced that their browser was outdated and missing several security features from Firefox. It's possible that the browser is fully updated now, as it does seem to be receiving updates regularly, but I currently have no reason to switch back to using it as my primary browser on android. Now, if they were to revert the UI back to previous one, I'd have a reason to use it again. I really don't care for the UI both Firefox and Fennec have currently on android.

Floorp, a Firefox fork. It's fine, just trying it out.

And Firefox on mobile.

Firefox and emacs-w3m. I keep trying Nyxt but it hasn’t stuck yet.

I use Librewolf almost always I try others just for comparison an fun, here are they:

• Librewolf: I use it for its privacy defaults and because it comes with no bloat and no nonsense.

• Konform Browser: A fork of Librewolf but based on Firefox ESR rather than the regular release and focusing in smaller settings improvements. I've talked to the developer and they are very nice and seem to fix issues rather quickly. By the looks of it I will be moving to this browser permantly.

• Ungoogled Chromium: For testing webpages, like styles and stuff for my blog.

• Glide Browser: Its basically the Vimium extension + BetterFox. It's stil in early developement and it looks promising. I prefer Librewolf settings better than Betterfox so this keeps me from using this one.

Primary: Zen Browser.

Reserve: Edge

Zen was the beginning it was little odd but now I love it. Fast, feels great to use and no nonsense.

I can't use either Zen or Firefox at work so there I use Edge. Edge is also a nice browser, I really like the sidebar for mail and drop.

Vanadium on secure mobile and Trivalent on secure desktop, and a mix of Fennec/Firefox and Chromium where required on casual mobile/desktop/htpc

Firefox. It's fine. The ai stuff is concerning , but nothing's caused me enough pain to switch yet

Firefox, librewolf and thorium if I absolutely must touch filthy chromium.

Ironfox mobile, Librewolf desktop.

Occasionlly Vivaldi if I have to use chromium for something on rare occasion.

LibreWolf is the only right answer.

Daily driving Mullvad Browser now, it’s Firefox based and has strong anti-fingerprinting and privacy defaults - it does break some sites though and is missing some QoL features but that’s the price you pay.

Zen, at least until Ladybird is ready.

Firefox mainly and some forks (Floorp, Librefox, Fennex, Ironfox) also Vivaldi

Mullvad on desktop rn

Firefox

If I need a Chrome based browser, such as for Keychron Assistant, I use Helium.

Edge

Waterfox and Zen. I switched to Waterfox a while ago and have had no problems with it. It's basically "Firefox minus AI," which is what I wanted it to be.

I started trying out Zen Browser a few days ago, too. It's another Firefox fork, but Zen is more willing to try new things with the UI. So far I like it.

So it's been Waterfox on Android and Zen on desktop lately. (Zen does not have an Android version.) They both support Firefox sync, and syncing works between the two of them. Pretty cool.

Firefox tweaked to the point it'd really make more sense to start with waterfox/librewolf if I didn't already have the momentum. Vivaldi is slicker, but I think it's important to support an engine besides chromium

Zen on the desktop, Firefox on mobile. Zen has quickly surpassed what I thought it would be capable of, and it keeps adding awesome UI bangers that I wish Firefox would have though of decades ago.

Firefox for the most part. Ladybird whenever remember to build it, and the site I'm visiting isn't too complex.

Waterfox desktop, Fennec mobile

Firefox on desktop with every non scummy blocker I can have on it.

Samsung internet on my Zenfone with every non scummy blocker I can have on it.

Firefox at home, IronFox on mobile, and Edge at work (not really my choice, but works fine).

I swapped to WaterFox for everything and I've been enjoying it so far.

Librewolf or Mullvad on desktop, Firefox on mobile. Downloaded Ecosia on mobile to try the search engine, so I’m trying out their browser too.

Zen is my default browser, is what I use on my Desktop and my Steam deck. I also use Firefox on mobile, cause there isnt a Zen mobile.

I use Safari on my iPad with uBlock Origin lite to watch youtube.

If I need to use a chromium browser, I currently have Helium installed, but I will probably grab Vivaldi as a backup browser.

I dont really have any plans to change away from Zen and Firefox, works for everything that I need, and anything that doesnt I kinda just walk away from. I also love the Zen interface and workflow.

Firefox on Android and PC

Orion on iPad

Firefox on Android, iPad and PC.

I use Mullvad on my PC and Brave on my phone and tablet. (Please, don't hurt me fellow Lemmings)

Firefox almost exclusively with the requisite plugins. Only using other browsers when a site requires it, like Safari on iOS, but that happens maybe 1-2 times a year. I don’t even have Chrome installed anymore.

librewolf on my personal machine and firefox on my work machine (I'm only allowed vanilla firefox or chrome on there)

Brave, Firefox focus, opera, and chrome(with js, cookies, and preloading turned off)

Firefox. Vivaldi. Firefox for anything important.

I use Waterfox on my laptop/desktop and Ironfox on my phone (with Chromium as a desktop backup, and Vanadium as a mobile back up)

Right now I use Vivaldi on my work computer. For my personal devices (MacBook, iPhone, two iPads), I've been mainly using Kagi's Orion browser for about a year. It's a WebKit browser but even on iOS it can run (some) Chrome/Firefox extensions, which I think is pretty neat. I also dabble with iCab. It's a very eccentric browser with an interesting history that goes back to the 90s.

Waterfox

I use librewolf and ungoogled chromium all day every day.

Safari, Firefox, waterfox and Vivaldi.

Librewolf and fennec

Vivaldi, as it isn't American.

Firefox-esr. This is the old stable branch of Firefox intended for corpo use. Solid, battle-tested.

The last switch I made was on mobile I went from Brave (for ad blocking) to Firefox since Firefox for Mobile has extensions and I found a good cookie whitelisting extension.

Mac and iPhone: safari. Mac secondary: mullvad. Linux: waterfox

Icecat for pc, lightning for phone

Firefox

waterfox and librewolf mainly.
links2 with -g if I am in a tty terminal.
Dillo for my super-minimalist setups.

Netscape Navigator

Vivaldi, so far very happy with it!
