When I tried to install the Adobe Flash Plugin, I followed the guide as usual (in fact, I've performed the installation of the plugin on Red Hat systems so many times, it has become second nature). However, I was greeted by an error message:
Transaction Check Error:
package nss-softokn-3.12.4-19.fc13.x86_64 (which is newer than nss-softokn-3.12.4-17.fc13.i686) is already installed
There appeared to be a clash between the 64bit (x86_64) and 32bit (i686) versions of the nss-softokn package. When installing 32bit software on a 64bit distro release, you often have to install some additional 32bit libraries to support the application in question. In this case The 32bit version of the nss-softokn package was required in order for the 32bit Flash plugin to be installed.
A bit of searching online revealed that the workaround was to simply downgrade the 64bit nss-softokn package to the same version as the 32bit package that yum was attempting to install:
[root@redpill ~]# yum downgrade nss-softokn-3.12.4-17.fc13

After restarting my browser, I was able to access Flash content online. The package manager even prompted me afterwards to upgrade the 64bit version of the nss-softokn back to version 3.12.4-19 and doing so seemed to have no impact on my ability to view Flash content.
