got nothing to do with bookmarks I think leesa. This issue is cross-browser.
I did some digging and apparently when I forcibly connect to "https://fordforums.com.au/ firefox warns me of a potential security risk ahead" and "secure connection failed"
Get the same "Warning: Potential Security Risk Ahead" whenever I type in
https://www.fordforums.com.au/
Clicking on advanced I get:
"Someone could be trying to impersonate the site and you should not continue.
Websites prove their identity via certificates. Firefox does not trust
www.fordforums.com.au because its certificate issuer is unknown, the certificate is self-signed, or the server is not sending the correct intermediate certificates.
Error code: SEC_ERROR_UNKNOWN_ISSUER
View Certificate"
The "Addtrust External CA Root" certificate appears to be expired, expiring in 30-05-2020.
Aswell as "Comodo RSA Certification Authority".
However "Comodo RSA Domain Validation Secure Server CA" is valid until 2029.
I think I found the problem.
Or rather Firefox did, good job Foxy. *Pats*
