Review for Keep in Taskbar by Iamapole
Rated 4 out of 5 stars
The only thing missing is that the add-on doesn't work with shortcuts. I would like the same behavior when I use the Ctrl+W or Alt+F4 shortcuts.
This review is for a previous version of the add-on (1.0).To create your own collections, you must have a Mozilla Add-ons account.
