Rated 4 out of 5 stars

Great extension, but do you know, in FF's later than 3.x, you'll get a double triangle icon (the one for the dropdown menu next to the three dots) when used together with many themes like for example Silvermel or Charamel?
Only the ugly default theme or Noia4 theme seem to really support your extension.

This review is for a previous version of the add-on (4.9.5.1-signed).
