i guess at some point #firefox changed
media.autoplay.enabled = false
to
media.autoplay.default = 1
it's counterintuitive but you want = 1 to forbid videos from autoplaying. also set
media.autoplay.allow-muted = false
while you're in about:config
whew, missed this
@gatewave I would think logic would dictate 0 for off.
@cambridgeport90 ...you would think, but 1 is the new winner
@gatewave Then somebody ought to change that in any descriptions of binary operations, then, right?
@cambridgeport90 firefox does lotsa odd things and i'm a mere user. i'm just glad there's an option that works!
i'd personally rename it media.disable.autoplay
@cambridgeport90 here are the specifics of the current implementation

to add to the user confusion the one we're discussing is the only non-boolean of the set
