Great but have some issues Rated 5 out of 5 stars

I love your extension. It's great but I have some problems. I even try new beta but didn't help. Unload wont work correctly. When I unload tab I got two tabs one unloaded and one loaded with wont work. Automatic unload removes tabs from seen them anywhere, I must restart firefox to get access to them. When I update firefox to beta 9 this extension stops working kind of. It seems like not everithing is unloaded. So I got back to beta 8. Please fix it so I can use beta 9 and future betas.
