I have installed Flash, and it is up to date.

If I wait for this screen to clear, I get as further message "We can't load the video stream you require".

Since updating my browser to Firefox Quantum, I can no longer play content fromABC iView.(www.abc.net.au/iview) When I try to open an iView stream, I get a warning that "This site requires a plug-in that may slow Firefox", and it requires Adobe Flash to be installed. I have installed Flash, and it is up to date. If I wait for this screen to clear, I get as further message "We can't load the video stream you require". This problem is not unique to my system, but to all other users of Firefox Quantum I have spoken to. Hoping you may be able to assist not only myself, but a number of other users as well. ABC Iview is a free to air repository of video streaming content from the Australian Broadcasting Corporation. Thank you, R.G. (Rod) Eagle
