Love it. Want more =) Rated 5 out of 5 stars

Loved it, it really is a great addition to Firefox's long list of to have addons.

Just a suggestion, since firebug shows what are the css declarations that are not in use on a given element, could it be possible to have a report that would tell me that the line-height on the class .xkcd is never used?

Thanks for contributing with your time and with this awesome plugin.

This review is for a previous version of the add-on (0.2.1).
