Rated 4 out of 5 stars

First, this is an excellent add-on! I have a highly customized interface due in large part to limited screen size on my laptop, that said I have all my "bars" reduced to one semi-busy but highly integrated bar at the top of the browser. I see there is a toolbar button that may be placed to my liking however when I restart the browser using either this add-on or manually through the browser the button disappears from my bar. If I turn on any bar not normally open the button returns in its designated space but now my tabs bar which is normally hidden with the Tabs Menu add-on has been made useless. The tab bar is back no matter what bar I opened to find/retrieve the restart button. While this isn't a critical error it is very inconvenient and makes the toolbar button all but useless to me. Again not a critical point it simply adds a click into the App Button to use the add-on but these should be relatively easy glitches to fix which will make this a 5 star app for me!

This review is for a previous version of the add-on (6.1-signed.1-signed). 

The toolbar button bugs should be fixed in version 7, please give that a try!
