This issue has started to become a problem over the last couple of months. Several websites that I log into frequently are no longer working with Firefox, or are not fully working.

For example, I can't use Firefox for these websites at all. AA.com (gives me a screen that says it's down for maintenance) bankofamerica.com (it allows me to start the login process but when it attempts the 2FA it errors out. ATT.com (everything appears to work, except the chat feature. If I log into att using safari (for example) there is a chat box in the lower right corner. The chat box is not there when I use Firefox.

This is starting to become an issue (and is very annoying) to where I may have to change browsers either to Safari (eh) or Chrome (yuk).

Are some of my settings set wrong? Is there another fix? or......


Thank you Elliot ...

I am posting two responses. The first may work on some websites while the second may work on the others.

Diagnose Firefox issues using Troubleshoot(Safe) Mode {web link}

A small dialog should appear. Click Start In Troubleshoot(Safe) Mode (not Refresh). Is the problem still there?
