start.mozilla.org/firefox reports "your connection is not secure"
After updating to Firefox Quantum 62.0, when I launch the browser I get an insecure connection warning....on the mozilla Firefox start page!
Your connection is not secure
The owner of start.mozilla.org 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.
Is Firefox trying to prevent me accessing it's own web page???
Additional System Details
- Shockwave Flash 30.0 r0
- User Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:62.0) Gecko/20100101 Firefox/62.0
There is security software like Avast, Kaspersky, BitDefender and ESET that intercept secure connection certificates and send their own.
- uses an invalid security certificate SSL_ERROR_BAD_CERT_DOMAIN
- configured their website improperly
