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?

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
