Twilio javascript sdk client - firefox problem

Question

I can not get the Twilio client to work with the FireFox browser. I tested with client 1.3 and client 1.4.

• The call goes through, but I can’t listen to the voice of the person being called. The called person can hear me.

• I hear DTMF tones with senddigits, but numbers are not sent.

My version of FireFox is 53.0.3.

Edit: Debug messages from the console log are enabled.
