I couldn't log into facebook for a couple days. I went into my Add/Remove programs to check it out because my daughter had been on my computer a couple days before.
Anyone having this problem needs to check Add/Remove Programs and see if something has been downloaded lately. I had downloaded a program to print coupons and also some kind of toolbar (can't remember which one.) I removed these and my facebook page loaded right up. Maybe this will help someone.
