SSL Labs server reports such as https ://www.ssllabs.com/ssltest/analyze.html?d=buy.itunes.apple.com
(sorry, link brken to make the URL readable) have *two* links to more info about secure renegotiation at https://community.qualys.com/blogs/securitylabs/2010/10/06/disabling-ssl-renegotiation-is-a-crutch-not-a-fix which no longer exists. Did you mean https ://blog.ivanristic.com/2010/10/disabling-ssl-renegotiation-is-a-crutch-not-a-fix.html ?
I note that, for very good reasons, https ://browsercheck.qualys.com/ cannot be viewed by firefox when security.ssl.require_safe_negotiation is set to true. If this becomes the default then firefox users would be unable to use browsercheck.qualys.com
