64 Bit Flash Player

In case you are having trouble with the flash player on a 64 bit PC, you can correct that by doing the following in a terminal:

Remove current installed version:

sudo apt-get purge flashplugin-nonfree flashplugin-installer gnash gnash-common mozilla-plugin-gnash swfdec-mozilla
sudo rm -f /usr/lib/firefox-addons/plugins/libflashplayer.so
sudo rm -f /usr/lib/mozilla/plugins/libflashplayer.so
sudo rm -f /usr/lib/mozilla/plugins/flashplugin-alternative.so
sudo rm -f /usr/lib/mozilla/plugins/npwrapper*flash*so
rm -f ~/.mozilla/plugins/*flash*so

Add sevenmachines' PPA (make sure all package managers are closed first):

sudo apt-add-repository ppa:sevenmachines/flash
sudo apt-get update
sudo apt-get install flashplugin64-installer

At this stage, you should restart Firefox and verify that the plugin is installed by selecting Tools/Add-ons in the menu.

Uninstall instructions:

sudo apt-get remove flashplugin64-installer

Flash was working very flaky before I done this, now it works perfect so far..
Thanks Wolfman..

Glad it worked for you. I had a problem myself and found the "cure" on the Ubuntu site.
