Chrome da best.
Firefox is for ricers.
Surviving even one Pwn2Own is a huge accomplishment. Chrome is very secure.
-BUT THREE?! My god. Now it just needs better add-on capabilities which I don't use much of.
For those who don't know what Pwn2Own is. In the gist, it's a hacking "contest" if you will, where hacking teams compete to see who can crack through the security of web browsers/phone OS's, etc. (times are also kept in mind).
For those of you that are going to hack at this post about "FIRE FOX HAS ONE MILLION ADD ONS", don't bother. You can buy a Honda, throw as many spoilers/stick on hood scoops as you want.. it's still FWD, and it's still slow from all that shit you've attached to it.
Firefox is still a decent browser as long as you don't rice it out.
