Parse firefox profiles.ini files to get paths of profiles. (#664) 
# Parse firefox profiles.ini files to get paths of profiles

This parses firefox profiles.ini files to get the paths of the profiles
instead of just treating any subdir of the firefox dir as a profile.

This allows supporting profiles without a dot in their name which the
existing glob didn't match which can happen if they are named manually,
as well as profiles configured to be outside of the firefox directory
that were ignored and profiles that are symlinked (by adding a resolve()
on the path before the is_dir()).

There is also an additional try condition to avoid failing for the
remaining profiles if encountering a profile without the
customChrome.css, as it might be installed on some profiles only.

## Changelog

- Fixed theming Firefox profiles that don't have a dot in their name
- Fixed theming Firefox profiles that are outside of the Firefox dir
- Fixed theming Firefox profiles that are symlinks
- Fixed failing to theme remaining profiles after encountering one on
which the firefox-gnome-theme is not present

Please note that I have only tested on non-flatpak Firefox.
