This add-on is really useful, but Firefox will run a little slower after installation, and toolbars will continue to break due to recent updates.
Even if you save the toolbar custom, it is not saved when you restart Firefox. (This is so annoying!)
Toolbar custom reset does not occur in previous versions.
