I'm not sure if it was an update to Firefox or a plugin, but Livestream videos no longer play in Firefox. Example page: http://livestream.com/accounts/11707815/events/4299357 I have streamed these videos before, with no problems. I cannot figure out what changed to cause this issue. The page loads fine, but the video does not. OS: OS X Yosemite (10.10.5) Browser: Firefox 44.0.2 Plugins are up to date for Flash (v 20.0.0.306), Java (version 8, update 73, build 02), and H.264 (v.1.5.3) Other information: YouTube videos play fine Apple movie trailers (http://trailers.apple.com/trailers/) do not play I can view the same video content in Chrome
