Though it isn't here on Mac Update yet, the Safari 5 iteration Of PithHelmet 3 is available on the developer's site and works like the charm it is.
I have been running PitHelmet for many years. Many years. It is hands down the most effective and manipulable content filter I've ever found. Yes, I've used Safari AdBlocker, and it doesn't come close. With PithHelmet I can seen absolutely nothing but the content I want to see on any site. Or, I can choose to see all of the ads, or all of a particular kind of ad. It's genius.
With each Safari whole digit upgrade, theres a brief pause in PithHelmet availability while Mike does his magic to make everything compatible, and each time, I am stunned by the ad content on sites I visit regularly.
No, I don't like this advertising paradigm on the internet. If I need to pay for access to content, I figure I can make that choice - and do, when the content provider lets me decide. I don't watch much broadcast tv, either.
