Why isn't audio available on Facebook videos viewed on Firefox?
I was attempting to watch a video on a Facebook page (I believe it was Harlequin flowers) and there are several videos, none of whose audio feed I can hear. I've attempted to correct the problem myself by deleting the Firefox cache and clearing the history. I've closed the browser and reopened it multiple times but to no avail. I believe I have all the settings right on Facebook as well.
I'm using the most current version of Firefox (67.0 (64-bit) and my laptop is a MacBook Pro running macOS Mojave Version 10.14.5
I would appreciate any response you can provide.
