Review for Disable DragAndDrop (Thunderbird) by Frank Altpeter
Rated 5 out of 5 stars
This addon is so helpful, exspecially when using touchpad it happens quite too often to accidentially move a folder, now this can finally be no more problem to me :)
This review is for a previous version of the add-on (3.0.0).To create your own collections, you must have a Mozilla Add-ons account.
