While you are in safe mode;

Try disabling graphics hardware acceleration in Firefox. Since this feature was added to Firefox it has gradually improved but there are still a few glitches.

Fred - this did not help.

You appear to be using Kaspersky security software.

We have seen reports that Kaspersky Safe Kids is causing issues with the Chase website.

• /questions/1306519 Specific webpage not displaying in Firefox 81.0, and auto update without permission

cor-el - thanks for your interest in my problem. I am using Kaspersky software, but am not using Safe Kids. I do believe the issue may lie with Kaspersky but I'm not 100% sure.

Update Kaspersky. If the problem continues, disable it.

Fred - Kaspersky automatically updates at least every 2 hours. It is always up to date. I certainly have tried diabling Kaspersky when doing online banking and the issue still persists. Any other thoughts.

Start your Computer in safe mode with network support. Then start Firefox. Try Secure websites. Is the problem still there?
