Librewolf, their devs seem hella inactive but their builds are automated. Tbh I would prefer a working arkenfox more. Made my own softening and install script but its pre-alpha and I will likely rewrite it again in some time.
Check out Mullvad Browser. It’s created in partnership with the Tor Browser, but optimized to be used for the Clearnet. You don’t need to use Mullvad’s VPN with it either.
This sounds like immature project drama. I've seen it before where there's a large, professionally maintained product and people make forks to add small changes and then different forks start fighting with each other over because it's their features and they don't want other forks to incorporate them. You should probably just avoid Floorp if possible.
My small concern with Librewolf is getting security updates quickly. Cool project though. As I understand, the team has been better about quickly patching security vulnerabilities in recently months too.
Thanks for the edit and link to discussion, I am a FireDragon (Floorp fork) user and it seems like this issue is in hand and I'm not going to be concerned for the moment.
I use Garuda Linux and FireDragon is maintained by the same people so it's been customised to have the same look. FireDragon was previously a fork of Librewolf (another fork of Firefox I have always liked), so I just switched over to FireDragon to try it out. I'd also used Floorp in the past and really liked that, so to have FireDragon and Floorp become one was really nice. FireDragon is nifty and has the privacy focus that LibreFox has. Garuda Linux is also a really nice distro and a lot of care and effort has gone into it - it also has a Plasma version for gamers... which is lovely for me. It's late and this is a dreadfully rambling answer... but hopefully you get the idea (roughly!) 😅
Some time ago, a bunch of really smart people wanted to be able to modify software, so it can never be broken since they can fix it. Thus began open source, which is having a piece of software tell everybody exactly how to make it. Meanwhile, many companies don't want people to modify their software, usually because they don't want people easily competing with them and bankrupting them due to creating a better modification. Such software that isn't open source is termed "proprietary".
Floorp was one of these open source softwares. Some ambitious Japanese people modified Firefox, added some features and customizations, and named it "Floorp".
Recently, these people decided, for whatever reason, to stop the public from being able to access some of the materials and configurations for making Floorp. They did this by creating a new "warehouse" to store these materials, sealing off the access to it, and replacing the original location of the now proprietary materials with a note that tells you the location of the warehouse you can't get in.
