Thanks Joey.
And I found the url for listing a server's tls extensions here:
http://possible.lv/tools/hb/?domain=yahoo.com
Do you know how we can enable/test the extensions using firefox or any other browser?

> Also, I have lost the url of a website
which used to analyze any given server ( eg www.yahoo.com)
for its supporting various tls extensions. You provide the
server url and it will display all the tls extns supported
by that server. If you know of any such url, could you
please help me with that also.
