Rated 1 out of 5 stars

I have a fairly complex folder tree. Was really hoping this would work when I imported all my emails to Thunderbird as all emails were marked as unread by default. I used MarkSubfolders which initially turned all the folders to read. This was great, however after a day or two some and at times all of the folders started to switch back to unread for apparently no reason. Since then sometimes the command does nothing when used and then at other times it has caused Tbird to hang. Not sure why this is, but it doesnt seem to be working quite idealy to say the least.

This review is for a previous version of the add-on (0.0.2).
