Screenshots

GlimmerBlocker doesn't hack into Safari, so GlimmerBlocker's user interface is a System Preferences Pane instead of being part of Safari's preference window. The following images show the System Preferences Pane.

Most rules just block requests, but you can add css and Javascript snippets to the pages:

The Javascript below is executed within GlimmerBlocker so Safari/NetNewsWire receives the transformed html. They don't receive the Javascript.

The history tab shows which URLs GlimmerBlocker has blocked or modified, and which rule that caused it. You can double-click a line to edit the rule.
