After upgrading from Firefox 5 to FF 6, certain sites will no longer load. These sites both use Typepad and that seems to be where FF6 hangs. Have not had this problem with FF5. Tried clearing cache, deleting bookmarks (to sites that won't load), and typing in address. That doesn't help. Sometimes, the sites load partly (i.e. with only words, no images); other times, load after a long time (several minutes); most often will not load at all.
