Rated 5 out of 5 stars

Great Add-on. Now updated so that all tabs have a close tab button.

This review is for a previous version of the add-on (2.7). 

Rated 4 out of 5 stars

Very useful Add-on with one major drawback (or possible bug) which is that when the auto-hide feature is enabled, only the currently active tab has a close (x) button (Mac/Firefox 4.) In other words, in order to close any other open tabs, that tab must first be selected and only then will the close (x) button appear for that tab. This is impractical because it means navigating away from the currently viewed page to close any open tabs. (Only with auto-hide disabled will all tabs appear with the close button, which defeats the purpose of this Add-on.) If not for this I would have given it 5 stars. I hope the developer will consider changing this behavior.
