Due to Apple’s new 64-bit environment Snow Leopard, some third party add-ons to might no longer work. For example Adblock for Safari only runs if Safari is reduced to 32bit running mode. I think this is ridiculous, so I’ve been looking for an alternative.

Glimmerblocker is a proper alternative to Burgersoftware’s AdBlock, and it runs in Safari’s 64 bit mode. It has capability to auto-detect: ads, and allows you to make a custom domain blocklist. Without changing it’s config, most ads, at default sites, were removed. Thumbs up!
