Rated 2 out of 5 stars
Seems like this extension needs some maintenance urgently, because after you've edited the toolbar
on top of FF13.x (i.e. removing or adding some icons) there's a strange and very annoying bar on the left of a currently displayed web page.
It's most obvious, if you've got the Noia 4 theme installed, because you can see a tiled bar on the left, but it happens with all themes, even with the default theme of FF.
It doesn't disappear until you restart FF.
It doesn't happen with the AIO-Sidebar disabled or uninstalled.
I'm on XP Home SP3, btw. ...
More stars to come for a fixed version.
