Just about 3 weeks ago, I noticed my facebook running really slow. Like it would lag, constant beach balls. This isn't limited to just one browser, but pretty much all browsers (Firefox, Chrome Safari) From what I can remember, it started when Facebook decided to switch to their new design. But I'm not sure thats the reason as some of my friends never mentioned anything about the slow down, or anyone else for that matter so I'm thinking its something on my end? I'm guessing might be a virus? I've ran disk utilities > repair permission and everything else. Even resetted SMC and PRAM, no effect. The lag is only with Facebook, everything else runs fine. Ideas?
