Hi I recently installed an IBM IPS device which allows you to inspect SSL traffic. The way it does this is a sort of man in the middle and this means you need to download a certificate from the device and import it into your browsers. The process is detailed here for various browsers: http://www-01.ibm.com/support/docview.wss?uid=swg27039297.

Now this works for IE and Chrome and up until a recent update Firefox. I now get the error sec_error_extension_value_invalid.

Any idea on how to resolve this?

Very helpful. It looks as though the CA issued by the device (XGS 4100) doesn't conform. Remediation is to lower the version of Firefox back to 28.0 which is the last version listed in the support matrix.

It is possible to disable this new feature by disabling libPKIX support, but of course this is not recommended for security and vulnerability reasons.
