I am increasingly unable to complete transactions using Firefox. I've been a Firefox users for years and I've never encountered as many problem as I am now. Websites give me error messages saying they are unable to confirm my log-in credentials, or something similar. I've contacted a number of vendors who say that they are noticing an increase in the number of customers saying the same thing. My only recourse has been to place the order on the phone OR use another browser. What's up? Thanks.
