Connection not secure error on almost all sites including google.
I get this error on almost all sites. Example below for a search on google.
Your connection is not secure
The owner of www.google.com has configured their website improperly. To protect your information from being stolen, Firefox has not connected to this website.
This site uses HTTP Strict Transport Security (HSTS) to specify that Firefox may only connect to it securely. As a result, it is not possible to add an exception for this certificate.

Thank you for the detailed information. The certificate says it was issued by:
lonbp00001_london_proxy Digital Engineering Services Royal Bank of Scotland, London
Is this a new installation of Firefox, or did Firefox performed a Refresh?
In order to trust a business proxy, you can manually import the signing certificate. Firefox can do that if you change this setting temporarily:
(1) In a new tab, type or paste about:config in the address bar and press Enter/Return. Click the button promising to be careful or accepting the risk.
(2) In the search box above the list, type or paste root and pause while the list is filtered
(3) Double-click the security.enterprise_roots.enabled preference to switch the value from false to true
Once Firefox trusts your proxy, I suggest flipping that back to false to keep Firefox isolated from possible fraudulent certificates injected into the Windows certificate store.

Excellent, that worked like a charm! Thanks a lot.
