PCLinuxos 2011 and Flash Crash

A while ago I upgraded Jane's machine to the latest version of PCLinux and then updated all of the software.  When she was surfing sites with Flash it would crash and nothing would work to enable flash.  I did the update to the latest version and it still didn't work.  I eventually found out that Firefox was pointing to the older version within the add-ons manager section (Tools, ad-ons, and then go to the plugin section).  After I disabled the older version of flash and restarted Firefox the Flash pages started to work.
