Flash plugin RPM installed but not being used by Firefix

[Gary Stainburn]

Hi folks.

I've followed the instructions to install the flash plugin by downloading the 
YUM version and then installing the RPM. I got no errors when doing any of 
this. However, flash still does not work in Firefox. If I do 'about:plugins' 
it isn't listed.

Any suggestions on what to try next. All I'm getting from Google is variations 
of the same instructions I've already done.
