Comment 10 for bug 728778

@Christopher:

Correct me if I am wrong: those instructions are for getting a backtrace when Firefox crashes. In this case Firefox does not crash, only the flash pugin crashes. Will those steps be useful in this case as well?

> + Could you please provide step-by-step instructions that lead to the crash?

I haven't found a sequence of steps that systematically triggers the crash 100% of the times. However any of the following will ALMOST always make the plugin crash:

A) 1. open www.youtube.com
   2. add some videos to the queue
   3. play the queue
   4. wait for the first video to finish (or skip to near to the end)
   => when the following video loads, the plugin will probably crash

or

B) 1. open www.youtube.com and play any video
   2. switch to fullscreen mode
   3. exit fullscreen mode
   => crash

The latter seems to happen especially if you exit fullscreen when the video is buffering, but this may be only my impression

I attach the about:plugin page as you asked
