An awesome but not perfect SEO plugin for Firefox users.

At first it seems a little daunting to use and adds a lot of information to the search results but once you get the settings right for what you want to track and play about with it you will start to wonder how you ever done without it. Allows you to easily do some fast competitive research.

Remember to read the installation instructions and set it to auto for the information you want to see and disable the rest to ensure the tool runs as fast as possible.
