Mark as Unread not working for me Rated 2 out of 5 stars

This add on has been what I'm looking for, except I can't get the PRIMARY reason I wanted it to work!!! I have my filters setup like I did in outlook rules, a new message arrives, move it to the right folder and mark as unread... the rule does just that but once it arrives in the folder, it goes from unread to read without me doing anything... who's got an idea? I think it's a Thunderbird setting, but I can't figure it out. Until then, I can't review favorably.

This review is for a previous version of the add-on (1.0.0).
