I started getting this message a while ago. It does not only appear with youtube.com i remember that it also appeared with google.com and probably some other websites. Not on all secure connections (https)

Message,

This Connection is Untrusted

"You have asked Firefox to connect securely to youtube.com, but we can't confirm that your connection is secure."

"youtube.com uses an invalid security certificate.

The certificate is not trusted because it was issued by an invalid CA certificate.

(Error code: sec_error_inadequate_key_usage)"

hello, maybe you can solve it by deleting the file in your profile folder that holds the certificates. go to firefox > help > troubleshooting information and click on profile folder/show folder. a windows explorer window should open up - in there delete the file named cert8.db & restart firefox afterwards (the file will be regenerated).

The file was regenerated. But after doing that if i try to open anything i get an error. But this time it is . (Error code: sec_error_untrusted_issuer)

So , I removed the newly generated file and got back the old one.

when you get the sec_error_untrusted_issuer error on youtube.com & you attempt to add an exception & view the certificate - which issuer name/organisation is displayed there?

more options

I did not try to add an exception.
