Some settings to check (in about:config):

media.autoplay.enabled -> false
media.block-autoplay-until-in-foreground -> true (probably not necessary
if you have the above setting)
media.default_volume -> 0.0 (or something suitably low so as to not be
obnoxious when you do start a video playing)

There are probably others, but those seem to do what I need (which
sounds similar to what you describe).
