I need to write some reviews to get some customer feedback on a brick and mortar store. I need to find a way to switch my IP address for this. I have a subscription with yourprivateproxy but I don't know what to do to accomplish the switching in my browser. I have only used my paid proxies for automated stuff. Scrapebox, and some forum submission. What is a good addon for Firefox. I looked at some and they seemed to have no way to input the proxies. I still keep IE 8? around too. Any ideas? What am I missing here? Thank you for your consideration.
