Two years ago I asked for help with a problem I was having on my grilfriend's computer (http://ubuntuforums.org/showthread.php?t=1966088). After upgrading to the latest Ubuntu (at the time) she was no longer able to play YouTube videos or anything else having to do with Flash. Someone did suggest installing an older version of flash using "Flash Plugin Installer" instead of "Adobe Flash Plugin". For some reason, that didn't work.

Fast forward two years and one angry girlfriend and I FINALLY found the issue. The guy suggesting the older version was right, but his fix didn't work. This one - http://www.linuxquestions.org/questi...us-4175420481/ - did and provides and explanation as to why - my favorite question.

I am posting this here some someone else doesn't end up on a two year search for answers as I did.
