Firefox on 9.04 won't play videos at YouTube

[Nikita Manovich]

Probably you have amd64 (em64t/x64) architecture... Please try the
following steps.

1. Delete all installed flash plugins for firefox browser
(swfdec-mozilla or flashplugin-installer).
2. Download the plugin for your x64 Ubuntu:
http://labs.adobe.com/technologies/flashplayer10/64bit.html
3. Go to terminal and create the directory: mkdir ~/.mozilla/plugins/
4. Copy the plugin into the directory: cp libflashplayer.so
~/.mozilla/plugins/
