So Firefox 3.6 scores 1.5, Firefox 7.01 scores 2, Chrome Win (14.0.835) scores 2.5, while IE 8 gets a 3?

Safari for Windows isn't even recognized.

Chrome 13 scores 2.5. I thought Chrome latest was 14, which definitely addresses some of the missing points from 13.

Neither is Opera. IE 9 gets a 4. (suprise?)

Your scores aren't necessarily representative for the browsers you mentioned, as the outcome of some of those tests depend on your browser/system settings.

The scores are predetermined, according to http://yourbrowsermatters.org/docs/methodology.pdf

Most of the security features that were included in the score are publically documented by the browser manufacturers and the presence can be verified directly through the browser itself. Additionally, tools like the Sys Internals process expirer were used to verify the use of DEP, Protected Mode, and ASLR.
