GlimmerBlocker: a more stable ad-blocker

Download for OSX 10.7, ..., 10.10: GlimmerBlocker-1.5.3.dmg (release notes).

To use with OS X 10.9 (Mavericks ) and 10.10 (Yosemite): You might have to download and install OSX Java from Apple first as includes a library which isn't included in OSX and which newer java versions need. If you upgrade from previous version of OSX, first install this library, then download and install GlimmerBlocker. Contrary to what the OS X installer tells you, GlimmerBlocker is NOT incompatible software but just need the java library to be installed.

Download for OSX 10.5 and 10.6: GlimmerBlocker-1.4.16.dmg (release notes). When installing GlimmerBlocker, you might be prompted to install Java. Some users need to re-run the GlimmerBlocker installer after the java installer is done.

Easy to uninstall if you don't like it anyway.

GlimmerBlocker is free: No payments required, but please help spread the word as ad-based sites would very much like to keep it a secret:

Compatibility

Parental controls: There is a bug in Lion's parental controls, which breaks using any kind of http proxy. You need to report this problem to Apple as they're the only one who can fix the bug. The more reports, the more likely Apple is to fix the bug.

There exist no version of GlimmerBlocker for 10.4 (Tiger).

About GlimmerBlocker

The problem with other ad-blockers for Safari is that they are implemented as awful hacks: as an InputManager and/or ApplicationEnhancer. This compromises the stability of Safari and very often create problems when Apple releases a new version of Safari. Snow Leopard doesn't support the InputManager-based blockers when Safari runs in 64-bit mode.

GlimmerBlocker is implemented as an http proxy, so the stability of Safari isn't compromised because it doesn't use any hacks. It is even compatible with all other browsers and other native Mac OS X applications which uses http, e.g. NetNewsWire. The proxy runs on the mac and not on a central server like most proxies.

You'll always be able to upgrade Safari without breaking GlimmerBlocker (or waiting for a new release); and you'll 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.

Because GlimmerBlocker doesn't hack Safari, there is a few things it isn't able to do: adding a block by right-clicking an image, stopping pop-unders, and filtering cookies from 3rd party sites. But you win a lot in stability, and GlimmerBlocker provides much easier methods for adding your own modifications to pages by adding css rules, pieces of Javascript or by transforming the html before Safari receives it. So I'll hope you're happy with the tradeoff.

If you can program in Javascript you'll be able to add your own modification to pages. See the included filters for examples, e.g. adding a download link to YouTube.

Share your filters

A set of default filters for common worldwide ad-providers are included in GlimmerBlocker. So out-of-the box it blocks most ads. If you still see ads on common, high-traffic sites, please notify me so the filters can be improved.

You can create your own filters and publish them using MobileMe or plain WebDav so other users can subscribe to your filter.

See the list of filters which other users have published.

You can setup iPhone/iPod to use GlimmerBlocker when they're using wifi.

How to develop advanced filters

In addition to just blocking ads, GlimmerBlocker can add css or javascript to the pages, can modify the content using Javascript, can modify the request before GlimmerBlocker sends it to the remote server, can specify which dns-server or http/socks5 proxy that GlimmerBlocker must use when fetching that specific URL.

Miscellaneous

Very short FAQ.

GlimmerBlocker is fully open source and is licensed using GPLv3. You can download the source, make your own modifications, submit changes, etc.

Older versions can be found in the downloads directory. Sparkle uses two rss feeds: official releases and beta releases. Even though the rss feeds includes a link to the new version, the easiest method to update GlimmerBlocker is to open the "System Preferences", choose GlimmerBlocker and click "check now" in the "Setup" tab pane.
