There's a link which if opened gives a security error like please enable tls 1.0, 1.1 and 1.2. On investigation, I believe it uses ssl 3.0 but when i enabled it in Internet Explorer and tried to open it didn't. Please respond. The link uses client network and not normal internet.

SSL 3.0 is deprecated and not available since more than two years. Even IE11 disallows it. You should definitely fix it.

Thanks for your reply. May I request you to guide me how to transfer the security from SSL3 to TLS 1.2 since this is an enterprise application and the client cost can be there. Also, can you help me with the browser and version that supports SSL 3 and is still available? I would be thankful.

Hi, in all current versions of Firefox 59.0.2 Release https://www.mozilla.org/firefox/all/ or in 52.7.3esr https://www.mozilla.org/en-US/firefox/organizations/all/ TLS 1.2 is enabled as default.

Please let us know if this solved your issue or if need further assistance.

security.tls.version.min is set to 1 at default which disables SSL3. SSLv3 was disabled by default as of Firefox 34 and later. http://kb.mozillazine.org/Security.tls.version.*

Is the site triggering a Firefox error page? If so, please click the Advanced button and copy/paste the more detailed error message there. This article describes the page I'm referring to: What do the security warning codes mean?
