Updated up to FF 3.7 Rated 5 out of 5 stars
Since the available version doesn't works with FF 3.6 I'd updated the .xpi file to make it compatible up to FF 3.7
It's NOT official but I'd NOT included any malicious code inside. Test it by yourself if you doubts!

For those who doesn't know how to edit & repack the xpi file by themselves. Tested by myself under FF 3.6 with no probs.
