Problem with quitting Firefox 4.0b8pre Rated 3 out of 5 stars

On my GNU/Linux installation, Firefox 4.0b8pre's process wouldn't terminate correctly out of having this add-on. It might be a conflict of sorts, but I'm not quite sure yet. My other add-ons enabled at the time were AdBlock, LastPass, NoScript, Omnibar (RDF-edited), Remove Tabs (RDF-edited), Status-4-evar, Stylish (RDF-edited), and Undo Closed Tabs Button. Otherwise, it does exactly what it says, and I'd love to see this problem fixed. Cheers!

This review is for a previous version of the add-on (1.1).
