There is usually a button to ignore this message and continue.

If websites complain about 128 bit encryption not being available then that can be caused by sniffing the user agent for "U;" that was removed from the user agent in Firefox 4+ versions. You can ignore this warning and see if it works if you continue. Firefox supports 256 bit encryption ciphers (AES-256) since 2003 in Firebird 0.6, so all Firefox versions support 128 bit and stronger 256 bit encryption (128 bit shouldn't be used these days anyway).

"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."

I'm not sure that warning is correct, since as far as I know, Firefox supports both 128-bit and 256-bit encryption. See: Does Mozilla support 128-bit encryption?

Did you try continuing and see whether you ran into any problems.

For what it is worth, the above mentioned browser check page shows in Tools > Page Info > General:

• Security information for this page
  Connection Encrypted: High-grade Encryption (TLS_RSA_WITH_AES_256_CBC_SHA, 256 bit keys)

I tried to continue and it just sat there - I can only assume its failing due to this "error".

Thanks for the replies - its an internal issue. NOT a Firefox issue.

I've no problem with clicking the continue button and get the login page
