Firefox Stable 21 occasionally pauses for 5-10 second in the DOTT demo.

Now consistently reproduced, the latest Firefox stable hangs on Windows 7 systems at least momentarily in the start of the DOTT cutscene where purple tentacle drinks the water. Audio also stops.

Waiting for 5-10 seconds resolves the block and the playback and audio continues.

Tested the latest Firefox nightly on the same computer, and it works without pauses, so this might be fixed in Firefox.
