Great simple extension, could use 1 more feature Rated 4 out of 5 stars
I was looking for exactly this plugin and liked it for 2 reasons:
1. it doesn't constantly slam the query servers - a quick click does an on-demand request for current IP.
2. it's so simple and not bloated.
I would give it 5 stars if it allowed copy/pasting of the address by right clicking, similar to the way ShowIP does (ShowIP shows IPs for the sites visited).
