Class A Extension Rated 5 out of 5 stars

thanks one of the best extensions, however, none of the additional menu items seems to work, most of them are actually useless, but items like INSPECT ELEMENT doesn't even work. also, firebug shows as "undefined" and doens;t work either. would be great if you can fix these issues.

This review is for a previous version of the add-on (0.7.8). 

Addon just adds items from main context menu, however there is no guarantee that items will work outside of the original scope.
Most of the Firefox commands are working. Third party addons may or may not work and I do not have a control over it. Usually I am contacting to the author or third party addon, some of them are fixing the issue. Please report exact items on the support site, I'll see what can be done.
