Hi Fred

Thank you so much for taking the time to look at this. I have a follow up question on this matter given your response.

Does this mean that my computer is infected and if it is how do I find and remove problem?

Your help is very much appreciated as I am not sure what to do.

Many thanks

I don't know. Further information can be found in this article; https://support.mozilla.org/en-US/kb/troubleshoot-firefox-issues-caused-malware?cache=no

Run most or all of the listed malware scanners. Each works differently. If one program misses something, another may pick it up.

This could be a problem with OCSP stapling.

Try to disable OCSP Stapling temporarily by toggling this pref to false on the about:config page to see if that has effect.

  • security.ssl.enable_ocsp_stapling = false

You can open the about:config page via the location/address bar. You can accept the warning and click "I accept the risk!" to continue.

It is best to reset this pref via the right-click context menu to true once you are done with accessing an affected website since this is a security feature.
