Review for Folderpane Tools by Sandra - Blog Diseño Web
Rated 5 out of 5 stars
Great extension. Please note that to sort your email accounts you need to go to Tools --> Add-ons --> FolderPane Tools --> Options. Once there, you can move up and down your email accounts.
This review is for a previous version of the add-on (0.6).To create your own collections, you must have a Mozilla Add-ons account.
