Vanilla Firefox. I trust Mozilla more than I trust the devopers of any fork.

Zen Browser is rather decent.

I'm using plain old Firefox, mostly because I don't know enough which forks are available as well as their tldr's.

Sidenote: Please tell me there's a (good) project named Firefork.

I've switched from librewolf to mullvad browser, it is tor browser minus the tor network.

In other words it makes all its users have the same fingerprint so that they can blend together. This is much more effective at detetring tracking than simply hiding or randomizing details like librewolf does.

In this thread the arkenfox Dev goes as far to say "PS: long term I am hoping we can retire arkenfox (I can't speak for LW) and just use MB - but they're just a little too divergent for now"

Other options (besides tor browser) are librewolf or Arkenfox, no other firefox forks are reputable from a security/privacy perspective

Vanilla FF here. LibreWolf was great but too many websites broke under it for some reason and didn't with vanilla FF even with all the privacy settings turned to 11.

Zen has been pretty nice, otherwise just Firefox.

Firefox with containers, uBlock Origin, and that extension from the EFF, privacy something. Forks would need to be from someone very trustworthy to gain the same trust Mozilla has earned from me over many years.

I use the vanilla FF but with this theme applied:

Firefox forks are nothing but Firefox with a user.js file added to it. Just use Vanilla Firefox with a user.js.

I think floorp looks interesting, but I haven't moved to it yet.

All I want is something that does a sidebar as well as Vivaldi. Why is a sidebar so difficult?

I'm using Firefox, I heard it was the biggest fork of Firefox.

Zen browser

I use Floorp (mostly because vertical tabs and the customization) with Add Water Flatpak that makes it fit in with the rest of my GTK apps.

Try using Chameleon extension to spoof the headers to look like vanilla FF on Windows.

Firedragon which is a fork of Floorp... love it

I use libre wolf . It's just perfect point to not be a border . For people complaining about it breaking stuff or saying is just a user.js , read the documentation

I use Floorp for the sleeping tabs
