Great add-on Rated 5 out of 5 stars
Works fine on Firefox, but doesn't work on SeaMonkey. I have tried both versions (this and the 1.x beta) on it and the icon is always gray on every site, please check it out as it an indispensable tool for me, thank you.
*** UPDATE ***
I managed to get the beta v. 1.0.0b3 working after playing around with the settings, but the new interface is a big change, and needs some time to get used to, anyway, great job, thank you.
