Good, but Rated 4 out of 5 stars

why wouldn't you make to show IP, location and provider without clicking? it would be very useful, or at least make this in options

Rated 5 out of 5 stars

Wonderful extension Rated 5 out of 5 stars

The information provided by this extension looks tidy and informative.
And the surprising spam check provided, it checks the IP (proxy) we use. Try it when you use Tor, I have fun to see who block who or what the others think about your current Tor IP. I rarely (never actually) met this kind of service.
Also extra plus from me that the main dev site looks well designed and not bloated.
