RTMPS fails in Win7 IE,Firefox & AIR if media server disables TLSv1

We have disabled TLSv1 on our media server and the server supports TLSv1.2.

RTMPS connection works correctly using TLSv1.2 protocol in Win7 Chrome and Win10 all browsers.

RTMPS connection fails(SSLHandshakeFailed) in Win7 IE, Win7 Firefox and Adobe AIR as these clients uses TLSv1.

Adobe staff have already replied below in another thread https://forums.adobe.com/thread/2042940

"Thank you.  We plan on making a change in our next major version of Flash Player (currently in beta) that will support TLS 1.2 on Windows 7 and above.  We were not able to provide support for XP or Vista due to lack of OS support."

Any update on TLSv1.2 support in Win7 IE and Firefox?
