Modding the Referrer if I have access to the machine.

Hello, I have access to a lot of computers. I had the idea to create a tamper monkey script to turn all Amazon links on a person's page into affiliate marketing links. It works however I am sure that Amazon checks the referrer so all the affiliate links that come from their own site are ignored. I thought about bouncing the user through a server controlled by me that would then immediately send them back to Amazon with my affiliate link but if the user doesn't have a fast connection, this would be problematic and would be visible to the user. How can I modify the referrer? I've seen this asked before but they didn't have the access I do.

Nevermind. Amazon does seem to care if it refers itself.
