Firefox stuff

hi folks, Well, Firefox news aint the greatest today... 30 vulnerabilities in javascript alone... seems that just a small javascript fragment can create a stack overflow and allow a root package to be dropped ... rats... Common Mozilla, you're killing us here.... They're calling it the next Internet Explorer ... :-( I do have a question... for some reason not due to anything I selected the "check for updates" help menu item is greyed out on Firefox... I am running 1.5.0.6 on Suse 10.0. The option for selecting updates is also greyed out... anyone seen this... maybe I've already been hacked... Thanks -- Kind regards, M Harris <><
