@34a949f1 I also don't like the Firefox situation on native Debian. You can run the latest from Flathub Flatpak repo or from Fedora's Flatpak repo. Flathub also has LibreWolf if you'd prefer a privacy-oriented Firefox spin.
@66bf1196 mixing distro repos doesn't seem very... clean. I settled for downloading the binary from mozilla and upgrading by hand.
@34a949f1 It isn't mixing distro repos. Flatpak applications are contained within their own filesystem using the same Linux namespace technology as containers. Whether you get the Flatpak application from Flathub's flatpakrepo or Fedora's flatpakrepo has absolutely no effect on the underlying host distro.
