title: Disable TLS 1.2 in Linux using any of the chrome /firefox
body: <p>I want to disable TLS 1.2 version of a virtual machine (linux). I was wondering if there are any commands to disable it . 
  In windows we usually go to settings>Advaced settings>change proxy settings>advanced  in the google chrome , in advanced tab I just disable the radio button. But in case of linux I'm not able to find any settings related to TLS .</p>
