Mozilla finally decided to include TLS/1.1 support in Firefox. However, most users won't benefit from this support, because it's disabled by default and enabling is not many people will and can do. To enable TLS/1.1 support, use "about:config" in the URL bar and search for the security.tls.version.max setting. Set its value to 2 (default is 1).

Happy secure browsing!

If the "security.tls.version.max" is set to higher than "1", the download from https will be very slow for Firefox 24 and 25.
