Rated 5 out of 5 stars

Oh I'm sorry guys but this is a firefox 3.0 only compatible addon, it was ported here because it is not available in the advanced user options in the installer. Reinstall firefox and go to advanced user and check it off there and reinstall if you are using the 2.0.0.x series.

This review is for a previous version of the add-on (2.0.0).
