Rated 5 out of 5 stars

It seems not to work with FF 20. But look at the developer site and download the latest version there. This works for me.

This add-on is simply great. Because of it it is impossible for me to move to a different browser.

This review is for a previous version of the add-on (0.14.2012122901).  This user has 3 previous reviews of this add-on.
