Please update to the most recent version of Firefox:

Version 37.0.1 reversed the ssl protocol. Otherwise please contact the admin of the server who hosts the website.

Firefox is already update to most recent version but still have the same issue. There is no problem with Host as it working fine with other Web browser's

Is that only happening with this one website?

It is possible that your security software (firewall, anti-virus) blocks or restricts Firefox or the plugin-container process without informing you, possibly after detecting changes (update) to the Firefox program.

Remove all rules for Firefox and the plugin-container from the permissions list in the firewall and let your firewall ask again for permission to get full, unrestricted, access to install for Firefox and the plugin-container process and the updater process.

See:


The website may try to fallback to TLS 1.0 in a way that is no longer allowed in current releases or may be using a deprecated cipher suite.

You can open the about:config page via the location/address bar and use its search bar to locate this pref:

  • security.tls.insecure_fallback_hosts

You can double-click the line to modify the pref and add the full domain to this pref. If there are already websites (domains) in this list then add a comma and the new domain (no spaces). You should only see domains separated by a comma in the value column.

You can open the about:config page via the location/address bar. You can accept the warning and click "I'll be careful" to continue.

If this helps then you can contact this website and ask them to look into this.

It is working fine after changing value in security.tls.insecure_fallback_hosts

Thanks
