I have Flash Player running on Firefox when I boot in Windows XP. Flash Player will not even show the icon in step 5 of the help page when I boot in Debian Linux v7.6, even though the page shows that I have the correct version of Flash Player (v220.127.116.116) installed. It is always activated when I start Firefox. Some quirk of Linux also installs Shockwave Flash v10.1 r999. Could this be screwing up Flash Player? Do I have to switch to Ubuntu or Red Hat to use Flash Player?
