Review for Mailbox Alert by Splat_NJ
Rated 5 out of 5 stars
I'm using version 0.16.1 with Tbird v3.1.15 with no problems. IIRC when I updated Tbird MA no longer worked. So for now I'm sticking with these versions.
This review is for a previous version of the add-on (0.16.1).To create your own collections, you must have a Mozilla Add-ons account.
