Needs compatibility update and a small fix Rated 4 out of 5 stars

I find this add-on very useful; however, it needs an update to be compatible with Firefox 5.0* and beyond.
It also needs a small fix to remove an extra menu drop-down (called "Menu") from the menu bar on the Mac version of Firefox, but this is minor and doesn't impact the usage of the plugin.

Please fix when possible!

This review is for a previous version of the add-on (2.2.1-signed.1-signed).
