Videos go black at some point during playback.
Partway into a video it blacks out. I was at this site:

I do not see any video at all on that page - only a blank space where it should be. It works with Safari.
That is an MP4 video played via a video tag with the HTML5 media player.
<video id="jp_video_0" preload="none" style="width: 640px; height: 480px;" src="http://traffic.libsyn.com/pswithmatt/0512_psm_cs6interface.mp4"></video>
The file plays fine for me on Linux.
You can check the Web Console (Firefox/Tools > Web Developer) for errors with playing this file.

These are the only messages in the console: Using //@ to indicate sourceMappingURL pragmas is deprecated. Use //# instead jquery.js:1 Use of getPreventDefault() is deprecated. Use defaultPrevented instead. jquery.min.js:3 Use of getPreventDefault() is deprecated. Use defaultPrevented instead. jquery.js:3
If I have another site's page open in a separate tab parts of that page get blacked out. If I have a separate window open (to make sure I could log in to support) the input fields won't work then I click somewhere else on the page the whole thing goes black. I have to close all sessions of Firefox to get it working again. I have no problems with Internet Explorer [cringe]. My OS is Win 7 x64.
You can try to disable OMTC and leave hardware acceleration in Firefox enabled.
- about:config page: layers.offmainthreadcomposition.enabled = false
You can open the about:config page via the location/address bar. You can accept the warning and click "I'll be careful" to continue.
You can try to disable hardware acceleration in Firefox.
- Tools > Options > Advanced > General > Browsing: "Use hardware acceleration when available"
You need to close and restart Firefox after toggling this setting.
Disabling OMTC did not help me. Hardware acceleration has never caused me any problems before. I see no reason why it would suddenly start causing problems. If it is something weird like cookies or browser sniffing, well, at least Safari works.
This seems to work for me, Thanks.
