Chromium is a magnitude more secure than Firefox. If you find a 0day in the Firefox renderer, bam, code execution with full user permissions. A 0day in Chromium renderer code is pretty much worthless. Firefox has zero additional layers of security. Chromium has a battle-tested sandbox which kills 99% of all exploits in the absence of an additional kernel exploit. Also note how none of the recent Flash 0days was exploitable on Chrome.
