Comment 72 for bug 133133

Since I am not a programmer, I cannot submit a patch. However, can't someone simply replace whatever is opening Nautilus with xdg-open? You don't even have to know how it works or where the files are.

Just to be clear though, anything involving xdg uses XDG standards. If one is curious, or simply wants or needs to know the standard, check out multiple publications at freedesktop.org.

I understand that Mozilla has abandoned Qt, but that does not mean that Linux distributions of Mozilla software should be Gnome specific. The point of the XDG standard is that anything following it should work for any desktop environment that follows it. Both Gnome and KDE follow those standards.
