Review for Empty 'em by Jem_W
Rated 5 out of 5 stars
Current version 0.78 works perfectly in TB 3.1.7. Issues have obviously been fixed. This is damn useful. Only niggle is the pop-up telling you the job is done could be faster (it animates a little slowly) - but that is a very minor niggle! I use this constantly.
This review is for a previous version of the add-on (0.78).To create your own collections, you must have a Mozilla Add-ons account.
