Rated 4 out of 5 stars

Great Addon :] It would be nice if i could have very small height of this bar (even without text). (i dont like when i have smaller content window)
There also is bug on win7 the forward/back buttons move on firefox menu.
Also when option "hide bar when there is only one group" should work with greater priority with option "display/hide bar when mouse enter toolbox". I mean it shouldn apear when first option is selected.
Good luck with improvement :]

This review is for a previous version of the add-on (2011.3.22.01.1-signed.1-signed).
