HTTP based ad blocker for Mac OS X

No hacks, no instability
Upgrade Safari whenever you like, no need to wait for an upgraded hack

GlimmerBlocker is no longer maintained and should no longer be used as web sites have migrated from using plain http to using https (i.e. encrypted) which prohibits modification by a proxy unless you resort to install custom SSL certiticates on the client.

You should use a browser extension instead.

It was made as a hobby project during 2007-2008 by Peter Speck. It features both a custom http server and http client and a Mac OS X control panel.

GlimmerBlocker did not only block requests but also allowed for adding custom css and javascript to the pages. It also allowed for modification of the page html before the browser receives the html, which made some modifications much easier than DOM based modifications.

Lion compatibility

Changed how the upgrader app is launched as previous method fails on Lion, making upgrades fail without any error message.

OBS: Please upgrade GlimmerBlocker BEFORE upgrading to Lion as previous versions fail to upgrade when running on Lion

If you have already installed Lion, please manually download and install GlimmerBlocker from the home page.

Apple's java installer will be launched if java is not installed. This launch will happen from both the GlimmerBlocker installer and from the GlimmerBlocker System Preferences Panel (in case of OSX upgrades).

Miscellaneous fixes

Allow https to port 311 (Apple Server Admin). Requested by Aaron Adams.

Assignments to gb.response.status were ignored.

Support "content-encoding: identity". Reported by TJ Luoma.

Workaround in validating keyword expansion urls as NSUrl doesn't accept '|' in URLs, which is used by Google Translate. Reported by Jeremy Helm.
