CloseReview for SMTP Control by David Anderson
Rated 3 out of 5 stars
I'm using Thunderbird 15.0.1. The plugin works, but 1) often requires two clicks on the send button before it sends and 2) makes Thunderbird crash a lot (at least, Thunderbird never crashed before I installed it, crashed a lot whilst it was enabled and stopped crashing after I disabled it).
This review is for a previous version of the add-on (0.5.1).To create your own collections, you must have a Mozilla Add-ons account.
