This addon is a good try and nice! Even it shows me the "no unread message...." message while there are some unread msg~ I think maybe something is wrong on my PC as others seem have it working fine....
Anyway, I would like to have some feedback:
1/ It would be great for next enhancement if the username & password could be retrieve from the local cache but no need to keyin

, because -
2/ The password is shown as plain text if you check it by searching "zimbra" on about
:config page~
It's understood this addon without further support, just want to provide some feedback and idea~
