ROBOTANK The transition to Snow Leopard highlighted for me the substantial advantage Glimmer Blocker has over other Safari ad blockers. While all Input Manager based plugins stopped working with 64-bit Safari, Glimmer Blocker continued to function without a hiccup. While I unfortunately had/have to wait for a couple other plugins to be updated, at least I didn't have to deal with ads. As for Glimmer Blocker having a less thorough filter set than Safari AdBlock, I've found that with some of the additional filters linked to on the GB web page installed, I've managed to get nearly complete ad blocking, so far only needing three domains on my own filter. Also, I've found that Safari's page loading speed with GB is far superior than with AdBlock. I suspect this has to do with the way ads are blocked, though I could be wrong. It looks to me like AdBlock loads the data from the ad server then prevents it from being displayed, while GB prevents the data from being loaded at all. In any case, I'm very pleased with GB, and I strongly recommend it over the existing alternatives.
