If you are using Google Chrome but missing AdBlock+ extension from Firefox, this extension will bring joy to your browsing sessions. By that, I mean, nevermind.
Extension is supported only on Chrome 4.0+ developer builds. For a good reason.
You can change your Google Chrome channel to DEV and get developer builds automatically.
(REMEMBER: This is ALPHA software, not even Beta, so don’t sue me if your facebook game terminates all of a sudden.)
AdBlock+ extension for Google Chrome does it’s job perfectly, based on lists and custom rules. (However, no content rating based blocking supported yet)
You simply install it and configure blocking rules based on any list you want. You can use just the custom rules of course.
For reference, here are some screenshots I prepared:
