I'm no expert but solved it on my system. Using the command below as was posted above (update-alternatives), I chose my third selection, /usr/lib/flashplugin-nonfree/libflashplayer.so with all instances of firefox closed. When I opened firefox (this is version hardy/3.0.10, my kernel's 2.6.24), went to youtube and tried a video, worked fine. Hope it helps someone.
