Does this message get shown for all https connections? If not, please check that the certificate and all of its intermediates can be found in Firefox's certificate store (Options > Advanced > Certificates). Please mention missing certificates here.

Hi,

This issue is visible only for firefox and mozilla domains and subdomains. When i try to download some addon or sign on sync or visit mozilla support page i have this message

The certificate is not trusted because the issuer certificate is unknown.
The server might not be sending the appropriate intermediate certificates.
An additional root certificate may need to be imported.

UPDATE,

I we found root cause for my problem. NOD32 version 9 for some reason blocked connection to firefox and mozilla certs. After i removed nod32 anti virus everything working normally
