Comment 3 for bug 304778

After sleeping on it and coming back to this report i realize my post was a little much. I realize you have installed Flash 4 times. The main point I wanted to make was that you make sure you remove any other flash plug-ins you might have installed, that is the sudo apt-get remove command. Also you didn't list what flash plug in you are using. The above post installs the flashplugin-nonfree, I would recommend trying that one. You don't need to install all the other packages if you don't want, sudo apt-get install flashplugin-nonfree, would be enough.

good luck!
