Ah.  Yes.  You’re quite correct.  Edge and Safari run it very well.  Is there some reason you’ve not provided your certificates to Mozilla for Firefox?

Good afternoon, 

If you are clicking on a link and getting that error message then it is possible that you may need to use a different browser to ensure that you have updated root certificates.   Our certificates are valid and up to date.

Apparently Firefox is not liked in the financial sector (see below). While I have access to IE, Edge, and Safari, I prefer Firefox, which encounters this problem regardless of what machine I use. I'm being told that I need to get rid of Firefox. Perhaps Mozilla would consider addressing this issue with the financial institution involved. However, I'm not able to access Mozilla directly. Perhaps this forum could get the issue to someone within Mozilla who cares. Here's the thread: -------------------------------------------- Good morning, [deleted], All bowsers, operating systems and mobile devices use an authorized Certificate authority program. These programs make these certificate available. It is not clear to us whether the Edge and Safari browsers you mention are on the same machine. We can say that if either of those browsers are on the same machine as the browser you are having certificate trouble with, we would consider that browser (Firefox) the issue. The corrective options we would consider are: · Run a deep Antivirus Security scan. · Remove Firefox from my system, Scan again · Use a different browser Please contact us if we can be of additional help.
