A major complaint for all versions of Safari on OS X is that there is no default ad-blocking. While there may be several good alternatives or hacks to get ad-blocking in Safari, there is one that doesn’t touch your Safari install whatsoever.
GlimmerBlocker works around having to hack Safari by implementing it’s ad-blocking via http proxy.
From their site:
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.
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.
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.
We will be trying it out and posting it to our Scripts/Plugins area if we like what we see. This is not by any means new, but a lot of complaints have been surfacing with Safari’s lack of ad-blocking in general, so we’re throwing it out there…
