How do I disable the warning Chrome gives if a security certificate is not trusted?

When you use Chrome's Options > Manage Certificates > Import where are you placing the certificate? On the "Certificate Store" screen of the import, choose "Place all certificates in the following store" and browse for "Trusted Root Certification Authorities." Restart Chrome.

"You can avoid the message for trusted sites by installing the certificate.

This can be done by clicking on the warning icon in the address bar, then click

""Certificate Information"" -> Details Tab -> Copy to file

Save the certificate, then double click on the certificate file. On the certificate window that opens, click install certificate, then walk through the install.

The next time you go to the site it should work fine without errors."

On OsX you should export your certificate from firefox and import on keychain under the login profile.

"In order for me to get this to work, I had to copy to file using the ""Cryptographic Message Syntax Standard - PKCS #7 Certificates (.P7B)"" option and check the ""Include all certificates in the certification path if possible"" box.

Then I imported using Cornelius' instructions and it worked."

If the site to which you go, your own server, make sure that you have installed the Self-Signed certificate or a certificate from a Trusted Authorities on your server. Some server software sets the default test certificate, which can not be added to the Trusted root Authorities certificate store.
