AdvertServe Geo Testing per Mike Cherichetti

Do you use AdvertServe to serve ads on your web site, mobile apps or videos? Verify that your ads are served correctly in various geographic locations around the world without using a slow proxy server. Instead, this extension makes your browser emulate a proxy server so it appears to be in another location. This makes testing go very quickly as you simply select a location from a drop down and get on with your testing in no time. It's faster too because it's using your Internet connection directly.
