I guess you've heard the good news, that Adobe released yesterday (November 17th, 2008) the first 64-bit version of its Flash Player for Linux-based operating systems. Until yesterday, 64-bit Linux users had to install the 32-bit version of the Flash Player, which was forced to work with the help of the NSPlugin wrapper package.
Moreover, the "grey box" issue in Firefox 64-bit for the Ubuntu 8.10 AMD64 (Intrepid Ibex) operating system is a known and unresolved problem, as is also the fact that users had to reload the web pages to see the flash content, or even to restart Firefox.
But no more!
