Review for Mailbox Alert by Firefox user 4848f9
Rated 5 out of 5 stars
The best add-on for Thunderbird! All is working well except one thing: Specific folder alert does not work if you are entered in that folder. So you need to be outside that folder alert to trigger.
This review is for a previous version of the add-on (0.17.0).To create your own collections, you must have a Mozilla Add-ons account.
