Firefox takes 100% CPU when H.264 video-playback

When I play H.264-videos on youtube or vimeo, my CPU-usage goes up to 100%(under linux). If the video stops, the usage goes back to 3-15%. I think this is caused by gstreamer, because if I disable gstreamer.support in about:config the high-cpu usage stops(vimeo-videos will stop work).

PS: On Firefox 30 aurora the bug seems to be fixed. Just dropped this here for other affected users. PPS: Old "ticket" was https://support.mozilla.org/questions/971722

Thanks for your fast reply, it seems to be fixed with FF28, on my tor-browser-bundle(FF 24.4.0 esr) it still consists.

Edit: http://vimeo.com/12046811 when I watch(for example) this video, the problem consists(even with a new FF profile).
