I'm having the same issue. I got FireFox1.5 to run, and i put the link to jre, but still getting issues.
as Trek1701 said, i'm getting the plugin_stack.trace file
I've tried to run the touch /.autorelabel
but it didn't change anything. I rebooted, del the old .trace and tried again, only to have it do the same thing..
and the about
lugins: command not found
