I wish not to see a London home page while in U.S.

Hi Michael, Firefox itself does not normally determine your physical location for websites. Websites such as Google or the Firefox homepage can use your IP address to estimate your location, and that can sometimes be incorrect even when your VPN is off. Could you check whether the problem occurs on other websites as well? For example, does Google also think you're in London? If it is only Firefox's New Tab/home page showing London, please let us know which Firefox version you're using and whether changing the Firefox language/region settings makes any difference.
