The name already tells everything Rated 5 out of 5 stars

Actually I was just searching for an extension, that allowed me to move the add-on bar icons, which already works pretty fine with this little helper.
But besides that it offers some other interesting features. So I also got back my sorely missed "New Tab" option in the tab context menu.
Personally I don't need the other options, but for everyone, that e. g. wants to move the Firefox button or to move the menu, this is the right tool. Just one little thing I noticed: It seems not to be possible to completely remove the Firefox button from the UI.

This review is for a previous version of the add-on (1.4.3).
