Summary
This review was originally posted on VersionTracker.com.<br />Wow! Works like magic. I'm not a Mac Techno-wizard nor do I begin to understand code. I had to hunt around in determining how to install this baby. Finally, a link in your feedback indicated that MacFixit had a solution normal speaking people could understand. They had a screenshot of Safari Preference Pane : MacUpdate:%20Ad%20Subtract%20Automatic%20Screenshot.webarchive (you must register) which indicated that you (1) Download Ad Subtract css code flie (2) Save it on desktop (3) Go to Safari Preference Pane (4) Go to "Advanced " options (5) Choose "Style Sheet" -Other (6) Select Ad Subtract css file from your desktop (7) Hit Choose button (8) Restart Safari and.......bingo! I previously used Safari Ad Block, but Yahoo found a way program ads around this program and invade my privacy by slamming my email box with ads. THANK YOU AD BLOCK GUY!!!! I owe you one
Nice!

Strictly speaking...

This review was originally posted on VersionTracker.com.<br />Strictly speaking, this is not an ad blocker, since the advert material is still downloaded. It's "simply" not displayed within the browser. Having said that, I tried it and found it seems to work very nicely. I've turned it back off for now, but will keep it on hand for, er, moments of desperation. :-)
Wonderful!!!

This review was originally posted on VersionTracker.com.<br />A wonderful replacement for PithHelmet...requires no configuration and doesn't mess with my cookies. Just to clarify, though: If you hit a page with blocked content that you'd like to see...change your Style Sheet selection to "None Selected," and the blocked content appears instantaneously...no quitting Safari, no logging out/in...instantaneously.
Wonderful!!!

This review was originally posted on VersionTracker.com.<br />By far the best-configured .css adblocking file I've seen. Manages to block pretty well any web ad without being so restrictive that it blocks legitimate content. An absolutely perfect companion to Omniweb's built-in ad blocking tools.
A must have addition to every computer in the house

This review was originally posted on VersionTracker.com.<br />This is a wonderful tool. You never know when some garbage will show up on the screen. Whenever my young son and I are doing research, looking for new games, etc., stuff I prefer he not see comes up. With this tool my worries are much reduced. It's very easy to turn this on and off as needed. Of course, it won't block stuff you are purposely trying to view, but this is great for those of us who choose to not see this stuff. The auther should put up a paypal account for donations.
Totally Awesome!!!!

This review was originally posted on VersionTracker.com.<br />Thank you so much for this. Pure genius. It works beautifully on just about any site I visit. This really needs to highlighted in red or made a sticky on top of everything. 20 star rating from me. I'm going to recommend this to everyone I know.

Developer’s Description

By Steven Jay Cohen

Safari ad blocker (formerly GoodVibrations.css)

Ad Subtract will work with Safari (for Mac OS X and Windows) as well as other browsers. Most of the CSS here will work on any browser. Any browser-specific code will be optimized for the WebKit/KHTML Rendering Engine. Safari, Konqueror, OmniWeb, and Shiira are just some of the browsers that use WebKit/KHTML to render pages. This file will be updated monthly based upon submissions from users like you. So, if you make personal modifications that improve Ad Subtract, please head over to the website and submit them as comments.
