Since the release of Hardy Heron it is possible to use the 64-bit browser, Flash, Java, and MPlayer plugins from the Ubuntu repositories. If you need support for more plugins and would like to install a 32-bit version of Firefox to accomplish that, then see the section below.

A 64-bit version of Adobe Flash is currently under development. In 2009 and early 2010, a pre-release version of 64-bit Adobe Flash was temporarily available. A new preview 64-bit version of plugin was made available in September 2010.

     rm -f ~/.mozilla/plugins/*flash*so
  2. Install Adobe flash plugin:
    sudo apt-get update

64-bit Firefox and 32-bit Flash plugin (RECOMMENDED: Officially supported by Ubuntu to the extent possible with Flash)

A fallback if the above scenario failed is Ubuntu-packaged 32-bit flash with nspluginwrapper. This option will provide more restricted functionality, for example, a number of flash-enabled web sites will fail in different ways.
