He mentions technical reasons to avoid it, but I can't entirely follow 
the discussion.

Can anyone explain succinctly why my FC5 can process a dozen updates a 
week, including kernel updates, but this one is "just too much trouble"?

Don't get me wrong, I don't even use FF--I prefer Seamonkey--but I would 
like to have the /current/ FF available, if nothing else, for testing 
purposes and for supporting people who are using FF2.

Does the Mozilla updater work under Linux? Even if it does, I prefer to 
use an yum/rpm-based install.
