What is GlimmerBlocker

GlimmerBlocker frees you from viewing senseless animated noise on web pages by blocking URLs and/or modifying html pages. It enhances viewing selected sites by modificating web page contents by e.g. inserting helpful links.

Other ad-blockers for Safari are implemented as an InputManager. Such awful hacks often compromise the stability of Safari. GlimmerBlocker is implemented as an http proxy, so the stability of Safari isn't compromised. You'll always be able to upgrade Safari without breaking GlimmerBlocker (or waiting for a new version); and to be able to upgrade GlimmerBlocker without upgrading Safari. This makes it much easier to use the beta versions of Safari and especially the nightly builds of ​WebKit.

Mac OS X 10.5 or later is required.

GlimmerBlocker is free. No payments required. Just spread the word.


The current official release is GlimmerBlocker-1.6.6.dmg (release notes). Installation is simple, but you can get detailed installation instructions.

GlimmerBlocker installs very few files, so it is easy to uninstall.
