AFAIK it’s maintained by a group called Ablaze and I think I saw them mention they are university students and opensource enthusiasts in Github discussions.

There are blog posts on their site about changes to their team and leadership. Their blog is in Japanese but I just translate it with Firefox’s inbuilt translator. So I don’t think it’s a single dev.

There’s a hype around floorp right now. Certainly because it’s new and it offers a high level of aesthetic customization.

Unfortunately it doesn’t work for me because:

1. it takes up too much RAM compared to others. Even though people don’t really care about that on modern machine it goes against my philosophy.

2. I’ve been tweaking Firefox for a long time to get the highest privacy possible but it was extremely painful and I don’t want to redo that with floorp.

3. my system look is extremely minimalist and I remove any visual effects in apps I use which would go against the point of floorp.

These are some reasons why I went with librewolf since it was released in 2020. It’s efficient, well maintained, kept up to date with the latest Firefox version, and most importantly to me: deeply respectful of your privacy. Their privacy approach is very well explained in the FAQ It passed all the EFF tests better than any browser I’ve tested after hours of tweaks.

This is only my personal experience and preference. Per the Floorp developer himself privacy is not given the utmost care and users should prefer librewolf in that regard. If you want to use normal privacy and excellent Firefox derivatives, with no doubts, floorp will fit your needs.

Printing like to dead trees?

You could just use the system print dialog instead of Firefox’s if that works better for you, I think it’s possible to set it as default.
