Starting Firefox 34.0 the vulnerable SSL 3.0 has been disable and TLS 1.0 is the minimum used by default. https://blog.mozilla.org/security/2014/10/14/the-poodle-attack-and-the-end-of-ssl-3-0/

The security.tls.version.min in about:config should be set to 1 by default which means TLS 1.0 is the minim,um and not SSL 3.0 which is setting 0 on preference.

Do you have Avast? as the https-scanning in Avast can actually make your connection less secure in some case and cause problems like this. So if you have Avast disable the https-scanning in Avast. Some other antivirus scanners may have an effect on this also.

Most SSL tests test servers, not browsers. Firefox has SSLv3 disabled and you can't enable it.

I have the latest version of Firefox installed on one of my pcs, not this one, running Windows 7 Professional. When I ran the SSL3 test it came back that my Firefox Browser is vulnerable. I have searched everywhere to find a fix for this and can't. Please help me with this. Thank you

Thanks for the solution James!!!!!!!! I wish I would have asked sooner!!!! I disabled the WebShield Scanner on Avast and I no longer see vulnerable when I run poodletest.com on all of my browsers
