Rated 4 out of 5 stars

Thanks for the Add-on, it is really sweet
Just one problem: the option "show close button on all tabs", that should be the default option, keeps reverting to "show a single close button..." every time I close and open FF again.
I am running the latest Add-on and FF 4.0.1

This review is for a previous version of the add-on (0.3.2011020301.1-signed).
