My Yahoo - Firefox compatibility issue?

My Yahoo has worked fine with Firefox until this morning (8/19/21). I am on Firefox 91.0.1, which I believe was updated yesterday. This morning I started getting the Secure Connection Failed screen when trying to access My Yahoo. I can successfully access My Yahoo through Chrome or Edge. Did the new version create a compatibility issue?

I do have McAfee Total Protection running also. I'm unaware of any recent changes to that.

Thanks.

Thanks Fred. Use McAfee but none of the ones you listed. When I clicked on the link from the error page it gave me the third item above. However, about an hour later it mysteriously started working again so the issue is done.

There is security software like Avast, Kaspersky, BitDefender and ESET that intercept secure connection certificates and send their own.
