Any reason why my facebook homepage is no longer displaying in either Firefox or Epiphany (http://www.facebook.com/home.php)

Update Manager ran on several of my PCs already today and now on the ones that have updated my FaceBook homepage loads, says "Done" but the page is Blank/Empty. I am running Jaunty on these systems and Everything else seems fine. Very strange that only appears to have affected the Facebook Homepage (http://www.facebook.com/home.php) via my bookmarks I can load and properly display every other page selected thus far without issue but I cannot get to/display my FaceBook home page...

Jaunty_9.04, Firefox-3.0, multiple PC's (two desktops, one Laptop)
