Update:
Works great now! Thanks to the developer for finding the problem and solution.

---------------------------
Old:
Displays notifications for new mail in all the subfolders of an account - but not for the inbox itself. The message "Notifications for this folder is turned off" is displayed. There is no setting to turn them on.

This review is for a previous version of the add-on (1.9.8). 

My add-on does not produce "Notifications for this folder is turned off" message, so it seems that this issue is not caused by GNotifier. Please create new report on https://github.com/mkiol/GNotifier or send me more details to gnotifier@mkiol.net.

UPDATE:
After deeper verification, source of the problem was identified and will be fixed in the next GNotifier release. Thank you Farbmond for your report and helping me in troubleshooting.
