my zip code keeps changing on Firefox but not on MS Edge
My zip code changes constantly when I sign into accounts such as Costco, Sams, Home Depot. I correct the zip and when I sign out and back in, it's changed again. I had Geek Squad run a diagnostic and they said it's a Firefox issue. When I use MS Edge, the zip code does not change. Can I get help with this issue?
