typing 2-3 words isnt something that abnormal users do. if installing something as basic as browser using CLI is hard for you, then youre better off not using computer at all. it literally takes less time and effort to open terminal and type few words (or just copy paste) and spam enter enter enter. you just need to change your perspective. downloading a deb/appimage/tar/whatever file or opening app store takes more time, clicks and effort.
edit : i use arch btw, installing librewolf seems easier on arch than debian. just type "yay librewolf" and spam enter key.
these days if i find any project exclusively active on socials like discord and twitter, and github forge, i quit using it. i mean i wont be registering an account there just for community support.
huh? what linux distribution are you even using? also librewolf is available in the flathub repository
