This has been driving me batty for the past week.
Internet Explorer and then Chrome stopped opening Facebook even via an SSL connection. The best I ever got was a view of the first block of posts on my timeline but without the ability to click on anything.
I tried clearing the cache, then deleting and rebuilding my Chrome profile, but this had no effect. However, in Internet Explorer I went to Tools > Manage Add-Ons and disabled all of them for testing. It turns out it did not like Script Proxy by McAfee. I now have Facebook working on IE. Now just to try and get Chrome working.
