I can not log into my American Express account. I had to use a different web browser to log in. This has NEVER happened in the past before and I have been using Firefox for years.

Please explain the problem in detail. What happens? What is/are the exact error message(s) ?


Many site issues can be caused by corrupt cookies or cache.

Warning ! ! This will log you out of sites you're logged in to. You may also lose any settings for that website.

If there is still a problem, Start Firefox in Safe Mode {web link} by holding down the <Shift> (Mac=Options) key, and then starting Firefox.

A small dialog should appear. Click Start In Safe Mode (not Refresh). Did this help?

While you are in safe mode;
