This is a great extension for those that work with the web as a developer or supporter. This Chrome version lacks some of the features of the original Firefox version, which is the only thing that keeps me from giving this extension five stars.

The abilities Chrome has built in are better than this extension.

Fantastic. I know it wasn't developed for this - but it's an awesome tool to help with investigating online fraud.
