I once thought the problem described in https://support.mozilla.org/en-US/questions/965548?fpa=1 has been resolved in version 23. But I find my big Javascript movies are not run as flawlessly even in version 27 as in Google Chrome and Safari. An example is http://aia.lmsal.com/aia_cadence/aia_0211_rdiff_orig_20120119_1145/AIA_0211_RDIFF_ORIG_20120119_1145.html. Try the Javascript version (621.83 MB). There are many frames with missing lower portions and that is so distracting that such a movie is almost useless to scientists. On the other hand, Safari, and especially Google Chrome, runs it without this problem. I cannot believe the Mozilla developers have kept this problem unattended for such a long time!

So the issue with that particular web page is that the player loads each image at a time. The frame rate is limited to the function call for the next image to load. It is limited to the network connection and image quality.

It is possible to debug this by adding a frame rate measurement http://programmers.stackexchange.com/.../whats-the-best-way-to-use-requestanimationframe-and-fixed-frame-rates

Does this also happen with a compiled video of these images?

Can you download the video and then use one of your players?

I don't think either of the network connection or image quality is a problem. I normally do not use network, i.e., run the movies locally, and no image has white blanks. Google Chrome runs these movies perfectly without bad frames. This seems to be the problem unique to Firefox, unfortunately.
