hello shyjith_ck, ssl 3.0 is disabled in firefox versions 34 & upwards by default. no legitimate website let alone a bank should still use this vulnerable protocol, please contact their customer service and complain about this issue - if you want to re-enable SSL 3.0, you can do it like this, which will make you vulnerable to the recently published poodle attack though: enter about:config into the firefox address bar (confirm the info message in case it shows up) & search for the preference named security.tls.version.min. double-click it, change its value to 0 and restart the browser.

You may need to look for security.tls.version.fallback-limit and Modify that from one to zero also. Otherwise it may still use TLS 1.0 at minimum.

You should reset these preferences so they go back to default after done to be safe.
