Review for Mailbox Alert by Rob
Rated 1 out of 5 stars
The plug-in is not reliable. Sometimes it will post an alert and many times it will not. Seems to work ok with inbox but not with folders. I am using gmail in imap configuration.
This review is for a previous version of the add-on (0.16.4).To create your own collections, you must have a Mozilla Add-ons account.
