Flash crashes on Non-HTML5 videos
Since I have updated Shockwave Flash, I am unable to play Non-HTML5 videos, the player crashes. HTML5 videos play fine. I have reinstalled Mozilla. I have double-checked Flash is up to date. I am unsure if Flash is shared with other browsers, but all videos play fine on Internet Explorer.

You can check for problems with current Shockwave Flash plugin versions and try this:
- make sure you have the latest Flash version:

https://support.mozilla.org/kb/upgrade-graphics-drivers-use-hardware-acceleration - disable protected mode in the Flash plugin (Windows Vista and later)
https://support.mozilla.org/kb/adobe-flash-protected-mode-firefox - disable hardware acceleration in the Flash plugin
