Hi jeremybow,

Firefox will match the level of encryption the website uses, and Firefox is capable of higher encryption than 128-bit (256-bit if that is what the website uses). I think it's probably a browser detection problem on the web site's side!
Please report back to us!

You can ignore such a warning in current Firefox versions.

If websites complain about 128 bit encryption not available then that can be caused by the "U;" that is no longer present in the user agent of Firefox 4+ versions (Bug 572668 - Remove the crypto strength token from the UA string).

Firefox supports 256 bit encryption ciphers (AES-256) since 2003 in Firebird 0.6, so all Firefox versions support 128 bit and 256 bit encryption.

I had a similar Warning - We did not detect that your web browser supports 128-bit high encryption. If you have trouble connecting after you click the "Continue" button below, you will need to upgrade your web browser to a version that supports 128-bit encryption. What should I do?
