One of the differences between Firefox and IceCat is the default value
of the "privacy.resistFingerprinting" setting in <about:config>. The
default in Firefox is "false", and the default in IceCat is "true".
I've found that some audio/video players that misbehave in IceCat will
start working correctly if you set "privacy.resistFingerprinting" to
"false". It might be worth a try.
