Excellent add-on provide all info about web page, Domain Name, IP Address, Server Location, and many more. 100% accesible info.

Works fine except it stamps the flag over the top of other addons that add icons to the address bar making them unusable, ie Feed indicator/Feed preview. Fix this and it may be worth using.

Must have for sysadmins and web devs!

Im fans of Firefox, The Flagfox is best on add-ons

Always like to know where the website is located, Flagfox works perfect.
