<![CDATA[TLS Session Resumption Tracking Vulnerability]]>According to recently published research, TLS Session Resumption can be abused to track browser (Opera and many others) across web sites.

How can Opera users configure TLS Session resumption to the recommended 10 minute threshold?

I've searched FAQs, can find nothing. Also nothing in the config setting of Opera itself.

Thanks very much.
