In Firefox, enter: about:plugins
in the url address/location bar. Tell us what you see for flash. Should
be something like:

Shockwave Flash
    File name: libflashplayer.so
    Shockwave Flash 10.0 r32

Then, if you have a flash plugin, go to: http://flash.com
and in the black box below "Adobe Flash Platform" you should get a flash
video & sound.

Also, please let us know if you are using a 64bit or 32bit version of
Ubuntu. Please provide the output of:

$ uname -a

And which version of Firefox:

$ apt-cache policy firefox
