secure connection failed
The Secure Connection Failed message (The page you are trying to view cannot be shown because the authenticity of the received data could not be verified) is now effectively blocking access to more sites than it allows access to. I understand the reasons for introducing this measure but since there's evidently such a vast number of sites that don't use the recommended tls protocols Firefox has now made itself unusable. I've spent the day switching over to Edge - not because I want to but because I find myself shut out of practically every other site I try to access with Firefox. It is not my responsibility to inform the owners of all the world's sites that they should update their security to fall into line with Mozilla's requirements. I do not have the power to do this. All I - and every other Firefox user - can do is change my browser. Please restore Firefox to a workable, usable state.

make sure use select no proxy:
or try this:
about:config > security.tls.version.max
and change the value from 4 to 3 then click ok.

Thanks, but this did not work for me.
make sure your system date and time are current.
and see this page:
My time and date are perfectly in order. When I try pippki/content/exceptionDialog.xul, even for a hitherto frequently accessed site like Transferwise, the Get Certificate button is unable to retrieve any certificate information and I'm unable to proceed. Other browsers continue to work perfectly.

Thanks. These final steps appear to have done the trick.
Re the Secure Connection Failed error, I get this on a regular basis when trying to access my NatWest online account (unlike the OP it never seems to happen with any other sites?) I am in agreement with the OP in that it should not be the users' responsibility to address this problem - Firefox needs to find a fix for this problem - there are millions of NatWest customers in the UK and they should not have to keep clearing their history/cache every time they try to access the site!
