Hi Jitender,

Starting with Firefox
version 34, Firefox blocks Secure Sockets Layer version 3.0 (SSLv3) to protect
your information from attacks. SSLv3 is a type of technology that some websites
use to connect to a server. It is no longer secure, which makes it easy for
hackers to extract your personal information during a connection.





When
you try to access a site that only supports Secure Sockets Layer version 3.0
(SSLv3), Firefox blocks it and displays a message, Unable to Connect
Securely, explaining that Firefox cannot guarantee the safety of your data
on that website because it uses SSLv3, a broken security protocol.



If
you see this message, please contact the website owner to let them know about
the problem.





Additional
precautions:   To
further protect yourself from attacks, keep Firefox up to date.

The simplest way to do this is to set up automatic updates:


1.Click on the menu
button , then
click Options.


2.Click the Advanced panel, then click the Update tab, and make sure that Automatically
install updates is checked.


I hope this clarifies your problem.

If you still need further assitance, leave a comment and I will get back to you.

Regards,
Lokesh.
