64-bit Firefox and 64-bit Flash plugin

Adobe has temporarily closed the Labs program of Flash Player 10 for 64-bit Linux to revamp it's architecture and release it with more native support. They have also removed the downloads link for older release of 64 bit packages. However, if you wish to have flash-plugin without installing 32 bit libraries, follow these simple steps:

1. Download 64 bit  plugin from this direct link (I'm not sure how long this URL will be available).
2. Uncompress the downloaded file and copy(as root user) the shared object(libflashplayer.so) to /usr/lib64/mozilla/plugins/.

Restart Mozilla Firefox and visit about:plugins to verify the plugin. The above steps have been tested in Firefox-3.6.4 running on Fedora 13.

Caveat: Adobe flash-plugin is not FOSS.
