Thanks to thethinker, yup, CIMB warrant portals does not work if the browser is Firefox.
BTW, a check with Bursa Malaysia warrant listing shows that the "complimentary period" message is no more! I checked the file creation date and it is 1 day after I posted my blog! Shit, is someone from Bursa is monitoring this blog?! With the current attempt to crackdown on bloggers, I must be careful. One can't trade if the authority harasses you.
