I manage seller accounts for several small online stores, and all of the owners have authorized me to work with their accounts. I set up a separate browser profile and proxy for each store because I don’t want cookies or device data from one account getting mixed with another. Before I move the active accounts into those profiles, I need to know whether they still expose my real IP or look like they’re all coming from the same computer. Is there a way to check each profile from a website’s point of view?
