Right-click the player and see if it says About HTML5 in the menu. If so go all UAControl on it. Happened to me as well, looks like youtube broke compatibility. |

It only says "About Adobe Flash 11.2.202.235" |

And you have reset media.webm.enabled to true in about:config? Also override options unchecked in YTF's options? For me the UAControl + Flash from the start works, prevents autoplay and autobuffering. |

Prevent both autoplay and autobuffering, used to work just fine.
media.webm.enabled is already true, and I tried UAControl with no success. |

Make a new Firefox profile, install uacontrol, greasemonkey and ytf (the latest one) configure it and try again. Try not to log into youtube, view videos as guest. UAControl string for youtube.com domain: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.9.2.28) Gecko/20120306 Firefox/3.6.28 If it works for me with my old profile, same software and OS versions, and same settings it should for work you as well. The only probable causes are bad settings in your main profile or youtube cookies. |

Works for me. Try the HTML5 opt in/opt out trick. |

It's the evil HTML5 player from YouTube that is simply impossible too get rid of on some videos. I have faced similar issue many times. The best solution is too clear all cookies from YouTube and login again see if Flash player will play it again or else go here:
Even if it says - "You are not currently in the HTML5 trial." it's sometimes a joke. Click "Join the HTML5 Trial" and click "Leave the HTML5 Trial" this should always work. Now all videos will use Flash Player at least some days :P |

Working good for me! |

Prevent autoplay should work now even with the HTML5 player. Temporarily disable other scripts/extensions to see if the problem is a compatibility one. |

I'm having numerous problems now too. First, I started having most videos require multiple page refreshes before the video would show up at all (video panel missing completely). Now, YTF is not keeping my options selected. I can go into the configuration panel and change things, but they don't save. I'm using the newest YTF version, this is on videos that are showing as flash when I right click, and I've tried the HTML5 trial trick. I have not tried uacontrol, because it seems a bit convoluted, and because, as I said, this is happening on videos that, as far as I can tell, are flash. I am using FF14, however, the initial videos not showing up problem started happening prior to that update (the settings not saving is brand new, however) |

@lern2swim: Make sure you are using the last Firefox and Flash Player versions: Flash recently introduced a "Protected Mode" for Firefox that can cause hangs and crashes. If the settings don't save in Firefox is because another script/extension is blocking it. I suggest disabling them temporarily to see which one is causing the problem. |

Turned it off for a few days; just turned it back on and the settings are now mysteriously holding. I'm still having the same problem with videos simply not showing up without reloading the page though. |
