After upgrading their Ubuntu 9.10 machine to 10.4 (Lucid Lynx), someone in my neighbourhood noticed that Flash had stopped working in Firefox. Googling around didn’t provide me with a solution, but reinstalling the plugin did the trick: # sudo apt-get remove flashplugin-nonfree flashplugin-installer # sudo apt-get install flashplugin-nonfree flashplugin-installer
