> this *is* on a 32-bit system. Yea, but on fedora 8 they still install a 32 bit nspluginwrapper by default (I guess the theory is that selinux can be more paranoid about the plugin helper than it can about all of firefox). Removing (via yum erase) the plugin wrapper helped me (though I seem to have found some flash apps that infinite loop anyway, even when running without the wrapper, but it seems to happen a lot more frequently with the wrapper).
