Rated 5 out of 5 stars

This is an excellent add-on that should come by default in Firefox. Tab scope lets you view thumbnails of your open tabs, open links from there and browse their contents. I find it really useful because I tend to open the links in the pages I visit in new tabs and with Tab scope I can see the thumbnails of these new tabs I just opened. In addition, I usually have many, many tabs open and, thanks to Tab scope, I can close tabs I no longer need from their thumbnails without leaving the current tab; as opening many tabs, the button to close them goes away and you need to go to the tab to close it, but Tab scope fixes this. Also, I can reload the page, go back or forward from the thumbnails. As I said, this add-on is excellent! : D

This review is for a previous version of the add-on (1.1.6.1-signed).
