I go to great lengths to keep my $HOME directory clean, so I wish it was possible to avoid littering it with ".mozilla". Installing Firefox as a flatpak solves that issue for the stable version, but there's no Developer, nor Nightly flatpak. Really hope we get those, one day.
Hello, @Jon! Good to see you here again. Please clarify the status of this idea. It's quite an essential feature for those who are on Linux and would like to help Firefox regardless of the distribution. I appreciate any help you can provide.
