When logging into a couple of secure sites I am blocked with the attached error message. I've seen others with the same problem but their solution, forgetting the site, has not worked for me. I've got this message when using the NFCU site, and now the IRS account site. Both sites work normally with Edge.

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

Thanks for the reply Fred. Doesn't look like AVG is the problem. I've only seen this on two sites: I suspect this one may be a Roboform problem. https://my.navyfederal.org/NFOAA_Auth/login.jsp?NFCUSIGNOFF=2

and This one only failed a couple of time today, and is now working normally. https://sa.www4.irs.gov/eauth/pub/login.jsp?Data=VGFyZ2V0TG9BPUY%253D&TYPE=33554433&REALMOID=06-00029c6a-0543-17b0-89b8-163b0acf40c7&GUID=&SMAUTHREASON=0&METHOD=GET&SMAGENTNAME=UOkC7yx4eMTO24FGxPfBRb5q3Mj3Xh3pyXfBEjYyHJ97nGCXu16wx5MzFHjfZmlG&TARGET=-SM-https%3a%2f%2fsa%2ewww4%2eirs%2egov%2fola%2f

The only reason I sought help here is that those sites work w/o problems with the microsoft browser.

Your screenshot shows a reference to an http url. Have you selected HTTPS-only mode on the Privacy & Security page of Options? If you have a problem with an https site, this article may shed some light: https://support.mozilla.org/en-US/kb/error-codes-secure-websites
