Just firefox really, never had any real issues

Firefox for Android doesn't use chrome and has extensions including adblockers

There is like 2 browsers, Firefox, or all the chromium based ones?

ironfox + ublock
fDroid repository = https://fdroid.ironfoxoss.org/fdroid/repo

firefox klar
for sites that i don't visit regularly which need java & cookies
fDroid guardianProject repository = https://guardianproject.info/fdroid/repo

I use the one that's funded by Google.

i use fennec f-droid with ublock origin and numatrix

I primarily use Firefox

Firefox. My daily driver is an iPhone and I just use Safari there, but we have uBlock Origin Lite now. But on Android it's Firefox with full fat uBlock Origin. As it happens, I'm on the Android device now! I love its keyboard so much. Apple couldn't make a keyboard to save their arse if it came to it.

Define "best"?

Netscape Navigator 1.0. I think there's probably an update for it now.

Ironfox I think

EDIT : typo

Ironfox is ok. Though it's not fully open source (the ui isn't) I use Vivaldi

This Iceraven fork thad adds OLED dark mode

Mull for everyday-use or Vanadium for pages which need a chromium-based browser

DuckDuckGo, i like the "burn everything" animation (and functionality, but mostly the animation)

Not much people know Iceraven, yet its pretty good android web browser I can trll. Extensions make it even better :)

Iceraven for browsing, Ironfox for anything that screams "don't open this", Fennec for stored logins only and Cromite if I ever needed a Chromium browser.

Waterfox. For really powerless machines dillo or "links2 -g."

For android I just use firefox.

I've liked to use Fennec for few months now.

Ironfox. Not particularly happy with it, though. Websites keep breaking.

IronFox with ublock origin

Every browser that I know of is open source. But I use Orion!

I use Fennec F-Droid with uBlock Origin, Privacy Badger, Decentraleyes, and HTTPS Everywhere.

Though sometimes I've contemplated switching to the Guardian Project's Firefox Klar

Firefox and DuckDuckGo.

Vanadium on phone and hardened Firefox on laptop.

On Android, I use Firefox. If Falkon were available on Android, I'd use that as well. I use both of those on Linux and BSD.

StartPage browser and one simply named Browser with a blue shield icon

Firefox since v1.0.1 RC :)

IronFox for Android, at least until Google blocks it, and LibreWolf for desktop.

Best is subjective and recommendations would depend on your use case. Iceraven is my primary.

I use Ultimatum. It's more sirious take on Chromium with extension support, which was only a test.

Vanadium for web apps, Cromite with auto delete for random websites, and IronFox with various plugins for web searches
