Weird tab bug Rated 4 out of 5 stars

This extension was updated recently, allowing its use under FF 7.0.1. However, the newest version seems to have a bug - when I restart Firefox with saved tabs, in every window but the first, the first tab doesn't show up on the tab bar!

I'm not sure why this should be related to this addon, but I've done testing with and without this addon enabled, and it's definitely something to do with this addon. Weird...

(I wouldn't normally post bug reports here, but I can't find any way to submit bug reports elsewhere. Sorry!)

This review is for a previous version of the add-on (0.2.1-signed.1-signed).
