Fedora 9 x86_64: use flash-plugin with firefox.i386 ro firefox.x86_64

I tried both firefox.i386 and firefox.x86_64 with flash-plugin from Adobe. I prefer the x86_64, because I found it:

• it runs faster than i386 version.
• it pulls in fewer i386 packages (61 vs 78).
• I had issues update firefox.i386 once in a while due to the mixed i386 and x86_64 repos.

Here are the instructions on

Installing firefox.i386 on FC9 x86_64 and adding flash-plugin to both firefox.i386 and firefox.x64_64.

However there seems to be a memory leak with the npviewer.bin that comes with one of the nspluginwrapper.
