OK, I stumbled upon this the other day (not to be confused with [stumbleupon.com]) and decided to download to give it a trial.

Anything that’s free and will help you avoid those god-damn phising assholes deserves my attention (and hopefully yours!)

Simple, just how we like it! If there isn’t any information about the particular site you’re visiting then the icon will be white.

And as a final note, have you noticed how many dodgy websites have a black background, whilst the safe ones have white? It’s like an old 1950’s western for God’s sake… =)[link]
