Firefox-based browsers

probably meant Gecko browsers (Firefox use Gecko rendering engine). Other browsers that use this is like Pale Moon, K-Meleon, and Waterfox

I just use one browser actually, Floorp. What I like about it it's the 'Profiles' feature, before Floorp I used Firefox, Librewolf, etc.

With Floorp I can just create another profile that it's like another browser. It's probably the best Firefox based browser but it's not very known.
