I know Firefox disabled TLS 1.0 and 1.1 support in recent update. But while visiting site with TLS 1.0 support, Firefox asked me to enable it. I accidentally clicked to enable it. But now I want to disable it again. How to do that?

Hello langalia.kartik,

You can check the values of the preferences :

security.tls.version.min

and

security.tls.version.max

As described in this article :
