In the other thread about this to which I replied, I tried to make clear
that this is the cause of the pluginreg.dat being trashed. You want to
have NOT checked the check now and/or make it the default. Gnome has a
script that can set this. Someone else posted it in another thread, but
I can't remember it. Also, the Gnome menus System->Preferences->More
Preferences->Preferred Applications->Web Browser can be used to set it.
Once you select Firefox, the command box should have "firefox %s".

Once this is set, starting FF should make a new pluginreg.dat if you
removed the previous one, IIRC.

In FF, edit preferences will get you to a place where you can fine tune
the plugin configuration.

I'm going from memory here. Search the CentOS archives for a previous
thread about this to find all the gory details. A search with my name,
and pluginreg and/or firefox outght to get you to it quickly.
