Perfect password according to firefox

I was going through bits of firefox code, and I found the algorithm used by firefox to measure password strength. You can find it in function setPasswordStrength() in this file : chrome://mozapps/content/preferences/changemp.js.
So point schema for password strength:

For length :       password-length*10 - 20   (Max 30)
For Numbers:    no-of-numerics * 10          (Max 30)
For Symbols:     no-of-symbols * 15           (Max 45)
For UpperCase: no-of-Uppercase * 10        (Max 30)

Your password strength is sum of all these points. So smallest password that would get 100 on password meter can be : AAA@@@ or something similar. But there should also be some criterion for the uniqueness of the characters.

Interesting read-on how to choose good passwords. that are also easy to remember. Please share your tips on choosing passwords [but yeah dont share passwords :) ]

    there is no sample password provided by firefox.. but any password of length around 8 and 2-3 numerals, symbols, uppercase each is considered good password (like a1B2c@D!)
    Actually this is algorithm used by firefox to assign password strength when choosing master password (In Tools->options->Security)
