I just started getting the "This channel isn't supported on Firefox" message for "abc." abc previously worked. All of a sudden, it's not working.
I'm running Linux Mint 13, Firefox Firefox version 19.0.2, Plex Media Server Version 0.9.7.12, and Plex/Web Version 0.9.9.11. All are supposedly up-to-date.
Does anyone have any ideas as to why this just started happening for this channel? I was able to watch abc TV shows with no problem until recently.
