Anyone who is familiar with the Internet and searching on Google is likely to have run across several geotargeted ads which serve up content based upon your location.

While those solutions certainly work and aren't too time consuming, the new Firefox addon, Google Global, allows you to perform those tasks with a couple clicks instead.
