Emilio Cobos Álvarez 9c22143224 Bug 1976297 - Restore localization of a few labels. r=stransky a=pascalc 
I thought the underscores were some sort of magic builtin, but they
aren't, they just indicate where the accesskey is, apparently. So we
need to localize them.

Restore the same localization that GTK used. The GTK 3 gettext domain is
hard-coded to be gtk30.

I could use the Firefox built-in localization mechanism, but that would
end up with a somewhat weirder setup if the locales are mismatched, so
preserve behavior for now.
