IE - Of 80 total vulnerabilities - 14% Extremely Critical, 28% Highly Critical
Firefox - Of 16 total vulnerabilities - 6% Extremely Critical , 13% Highly Critical
The numbers speak for themselves...

Actually they do -- thanks for pointing that out. You neglected TIME (length of each app on the market, and time taken to isolate and fix the vulnerabilities.) The numbers says that 80 vulnerabilities in Explorer and only 16 have been fixed in Firefox. This pops the myth "that open source is more secure" because Firefox has been around a lot less then Explorer and still major vulnerabilities have been found. It would be an interesting data point to discover how many vulnerabilities Explorer had in the same time period as Firefox.

I believe Firefox is based on the Mozilla/Netscape code and has been around for quite a while...
