Flagfox is what Firefox extensions are all about: ultracompact, free, open-source, and uniquely useful. When you visit a Web page in Firefox, Flagfox identifies the country hosting the site's server with a small national flag in the address bar. You can customize the information Flagfox retrieves and displays, too.
We've used Flagfox for several years and always found it useful (and occasionally comforting) to be able to see at a glance where the site we're visiting is hosted, not to mention the bonus of learning to identify some national flags. Flagfox does a lot more than that, though, and we recommend it to all Firefox users.
Flagfox is an extension that will display a country flag in the status bar and thus showing the location of the current Web site's server. Flagfox uses relatively little resources, and works by accessing an IP address database contained within the extension rather than relying on top-level-domain roots like .com or .uk. Clicking on the icon brings up further information from Wikipedia or Geotool, which is an online Geolocation tool. Geotool attempts to get more information from the Web site's IP address, such as ISP and city and shows the location on a Google Map.
