very nice! Rated 5 out of 5 stars

Thank you! This is a simple addon, and that makes it elegant and lightweight, which is how addons should be, right? The old fix for doing something like this involved editing a css file in the profile directory, and that fix stopped working many versions ago. Finally I've found something that shows me all the tabs I have open. Very nice indeed!

This review is for a previous version of the add-on (2.0.1-signed.1-signed). 

Thanks for installing my addon. It is kept lightweight to have a minimal impact on the performance of the browser. FYI editing the CSS file still works.
