Doesn't seem to be working in later Firefox versions (11+) Rated 2 out of 5 stars

Sadly doesn't seem to be working in later Firefox versions (11+). "Tab Utilities" has an option for this also I think, but it also doesn't seem to be working - http://forums.mozillazine.org/viewtopic.php?p=11976311#p11976311.

This review is for a previous version of the add-on (2).
