Very handy! Rated 5 out of 5 stars

This is really very handy, especially because it gives the versions and browsers something does work or does not work. Hope you can add IE 8 soon.
And maybe you can make something similar for CSS?
One thing: why do you use two names? It's very hard to find this way.

This review is for a previous version of the add-on (1.0.1).
