Since a lot of us are probably looking for Firefox alternatives right now in case Mozilla does some nonsense in the future: The Arch Linux wiki has a list of webbrowsers for Linux at https://wiki.archlinux.org/title/List_of_applications/Internet#Web_browsers and the best thing is it's sorted by type, so it's quite easy to see which ones you even want to try in the first place. :)
