I was using a VPN set to Canada a little ways back, and now Firefox seems to believe I'm forever in Canada. Any time I go to use the default Amazon search included with the browser now, it defaults to Amazon.ca rather than Amazon.com. I've tried going to Amazon.com directly and manually adding the search, but that just gives me an error message. I don't have anything set to Canada at all anymore. How do I get my Amazon search to go back to normal? Is there something on the back-end I can edit to fix it?
