Can't close tab Rated 4 out of 5 stars

Marvellous add-on, I find it very useful. However, I have encountered the same problem as creib. Sometimes a tab becomes disabled, by which I mean that clicking on it doesn't focus the tab and it refuses to close. I've disabled image tweak for now, waiting eagerly for an update that hopefully fixes this annoying bug.

This review is for a previous version of the add-on (0.22.1-signed.1-signed).
