Hi. I can log into Hotmail, Gmail and Facebook on my Macbook, using Firefox or Safari, but then that's it. The pages stop loading and I can't do anything like read a message or post a comment. All other websites work, so it's not an Internet connection problem. I've erased cookies, cleaned out my cache, changed my MTU, DNS, etc., but nothing works. I've also scanned for spy software and found nothing, which leads me to believe the problem has to be with my Macbook/operating system. Does anyone have any suggestions, as it's been like this for a week and I'm desperate. Thanks!
