Rated 4 out of 5 stars

well,
windows users seem really pleased with your add-on, but linux ones... not that much! ;-)

on your mozdev website it's said that you don''t know how to implement kde/gnome integration
"new mail icon" add-on does that (actually it no longer works for me)

see if the author may help you if you're interested

cheers

This review is for a previous version of the add-on (1.2.1).
