Flash Video Stopped Working After Firefox Crash

Woke up this morning to find that Firefox 4.01 crashed overnight. Restarted a new session and discovered that Flash Player was not displaying on YouTube and other sites using Flash. Updated to the latest Version of Flash but no good. Turned off ad blocking but no good. I can hear the audio playing but there is no video and usually the player itself is invisible. Sometimes the area where the player should be shows a momentary black box. Flash is working correctly on my other browsers. I've cleared my cache, made sure javascript is enabled. Any sugestion?

I found a fix -- I went into the add-ons and disabled flash -- I then searched for flash add-ons and added the flash resizer 1.4 and restarted -- went to ebaumsworld and loaded up a video -- which of course didn't load because I had flash disabled -- re-enabled flash -- and it worked! --- I did notice if I disable flash -- then I have to repeat the entire processes -- including removing the resizer add-on. Hopefully that helps some of you as well.

Update: -- the above is still working -- but I did have to disable/restart/enable the resizer add-on once already as it stopped working again.
