I work for a video company encoding videos, The only problem we have is Firefox not playing videos encoded as H 264 (1080) larger than 2 gb, as they won't play. I Tried both current version 9.0.1 in mac and windows and no change. In IE, Chrome, the video plays fine. Is there a file limitation in Firefox? as I read someplace else that FF also has problems uploading 2 gb files, don't know of that's related. Any help would be appreciated.

Firefox doesn't even play H264 content by default. For HTML5 video it will play OGG / Theora and WebM, but a plugin is needed for H264 content.

ok, I'm corrected that HTML 5 support for h264 is not present in FF at the moment. SO if the Video hand-off to flash to play the video in Firefox would be the cause of the File size limitations, then it's Adobe's issue then, correct?

Sorry, Mozilla is never going to support H264 due to it not being free and/or open source.

Sorry, I have no idea about a 2GB limit, it there is one.
