Not Rendering in FireFox 40.0.3

This plugin works great with all browsers except FireFox (the new IE). All of the code is visible on the page but it will not render the CAPTCHA box.

I have disabled all plugins and this is still the case.

The only error that I’m getting that makes any sort of sense is this:

Error: https://www.google.com:443 uses an invalid security certificate.

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.

(Error code: sec_error_unknown_issuer)

I’m using the plugin on an WPMU network, and as previously stated, works GREAT even in IE!!! Just will not render in FF.

Any help would be greatly appreciated!
