Guide Review - ShowIP

ShowIP is a fairly simple extension but can prove to be a very useful one. The IP address of every web page that you visit is prominently displayed in Firefox's status bar without getting in the way. Color coding allows you to display IPv4 and IPv6 differently, and the style of all IPv4 addresses can be configured to your favorite standard. The custom menu queries, with the exception of the ipv6tools that require a monthly subscription fee, come in handy from time to time. I recommend removing those that are not free via the Services tab in ShowIP's Preferences. Also, the ability to add your own queries with parameters is a nice touch. This extension isn't perfect, but it gets the job done at the lowest level and makes a nice addition to your Firefox browser.
