Adobe has recently released a 64-bit version of their Flash plugin.  The new plugin offers a much needed improvement in performance compared to the "fixes" people have been using, mainly the nspluginwrapper.  This allowed a 32bit plugin to be used in a 64bit browser.  This is a first step in allowing users of various 64bit OSes such as Ubuntu and Vista, to use a 64bit version of their favorite browser, such as Firefox. 

In order to install the 64bit flash plugin, you need to remove the 32bit flash plugin and the nspluginwrapper that is used to "wrap" the plugin in 64bit Firefox.  Run the following commands:

sudo apt-get purge flashplugin-nonfree nspluginwrapper

After that flash should be uninstalled from your system, as well as the nspluginwrapper that was used.  Now you can download the plugin from adobe:

You have a few options as to how you want to install the alpha plugin.  One applies if you have multiple users, the other if you have multiple users using the system.

Single User System:

1. Create a folder call "plugins" in ~/.mozilla/.

2. Copy the libflashplayer.so from the archive to the folder.

Multiple User Setup

1. extract the file to your desktop.

2. In a terminal window type in:

sudo mv ~/Desktop/libflashplayer.so /usr/lib/mozilla/plugins/

After you have done one of the above steps, open up Firefox, and in the address bar. Type in "about:plugins" without quotes, and you should see something like:

Shockwave Flash

File name: libflashplayer.so

Shockwave Flash 10.0 r45

You have successfully installed the plugin.  Browse your favorite sites with a boost in flash performance!
