Rated 3 out of 5 stars
I wanted to revise my original review, but can't because the site won't allow it for some reason. So here's another one. Be advised that when you run this extension, it also compacts all of your folders. It also removes the "Empty Trash" item from the "File" menu dropdown. I'll probably still continue to use it, but it would be better if it only emptied the trash and left that menu item alone. There is no support option for this extension either, no way to contact the author that I can find.

Very happy to see this extension and my sincere thanks to the author. My only suggestion is that the button label be changed simply to "Empty Trash". I use the toolbars "icon and text" setting, so this would take up less space.
