[Bug-gnuzilla] Icecat SSL warning/error pages; what settings affect the production of these 'error' pages?

[bch]

Hello - not a bug, just a request for info really if any one can help please.

Occasionally (or is it regularly) I get some ssl warning pages displayed instead of access to the site when browsing with Icecat 45.5.1  (on linux 64bit).

An example message is pasted below. 'Trying again' does not help - the site is blocked.

I do not get these pages returned for the same sites when browsed using Firefox.

In some cases, Icecat reports an unsafe/unencrypted session and no valid or invalid certificate is available, when Firefox states for the same page it is ok (and I can browse the certificate details etc).

I did notice during one of these scenarios, that Firefox was reporting TLS1.0.  It led me wonder if it is a settings issue on what level of ssl components are acceptable.

Is Icecat setup by default to be less forgiving towards what it receives SSL wise, bearing in mind I have not changed any ssl related settings in either  browser?

Thank you for any comments/ideas.

Best wishes to all
