XFINITY TVAPP Error 00407 & 00408

Dear Mozilla,

No Xfinity video plays on my ’15 iMac/FF 59.0a1. Amazon, Netflix, etc play well.



installed and apparently up-to-date

Safari plays all subscriptions well.

Xfinity help desk could not detail the error codes. Resetting the modem and the router did not gain my iMac access to Xfinity video. Xfinity video works well on televisions in house.

Awaiting your reply, I will watch Xfinity on Safari …

Thanks !
