Corporate Firewall
Like several people have mentioned in other threads - my corporate firewall blocks, among other sites, Facebook. FlyerTalk used to be one of the few sites I could freely access from my office computer.
Now when I try to access each page, the top bar, up until the Facebook link portion, loads and then the page load stalls for a matter of minutes until (presumably) the call to Facebook times out, and then the rest of the page loads.
On at least one try I've counted at least two minutes trying to load a single page. If there isn't a way to disable whichever portion of the code is making a call to facebook.com during the page load, I'm guessing that any of us behind firewalls that block facebook will not practically be able to access FlyerTalk.
