Review for Get Selected Mails by Defrilitus
Rated 5 out of 5 stars
Says exactly what it does and does exactly what it says, which I think is the best review that one can give an add-on. Should be a default part of Thunderbird.
This review is for a previous version of the add-on (0.10.2).To create your own collections, you must have a Mozilla Add-ons account.
