If your browser breaks I hope another profile is not broken? Running 4 browsers at a time is seriously problematic for RAM, attack surface, updates etc.
I will do a post on introducing firefox profiles (as they are hidden away) and GUI integration into desktops
They have an Ubuntu PPA which I used through distrobox. The weirdest way to get an app on the system, while there is a flatpak they dont seem interested in adopting it.
Interesting. KDE too but you also have a button. Makes more sense to control windows through buttons instead of a button, a doubleclick on a bar and a keystroke (meta)
No that clears browser data, the fingerprint is very complex. If you mean cookies, Librewolf and Firefox can delete all but you can add exceptions where you want to stay logged in. Very handy, also not there in private browsing.
Uhm that site has no https and redirects somewhere else, dont feel like enabling javascript for that one.
And Ublock blocks it too. So yeah not a positive example
