Can't log into Americanexpress.com with Firefox

When I try to log into my AMEX account with FF, nothing happens. The screen refreshes itself, but no log in, and no error or other kind of message. I have entered my User Name and Password manually and using Auto fill, no success.

This problem was posted in January 2020 and I have tried all of the solutions. I have cleared cookies and cache for ALL sites and cleared saved logins for Amex. Still does not work. I have tried logged in and incognito mode. Still doesn't work. I can log in on Chrome with no problems.

It was working fine a few days ago.

Thank you so much for help!

Any relevant-looking messages in the Web Console that look related to this issue?

You can check for issues with Total Cookie Protection.


You can remove all data stored in Firefox for a specific domain via "Forget About This Site" in the right-click context menu of an history entry ("History -> Show All History" or "View -> Sidebar -> History").

Using "Forget About This Site" will remove all data stored in Firefox for this domain like history and cookies and passwords and exceptions and cache, so be careful. If you have a password or other data for that domain that you do not want to lose, make sure to backup this data or make a note.

You can't recover from this 'forget' unless you have a backup of involved files.

If you revisit a 'forgotten' website, data for that website will be saved once again.
