Wouldn't newly opened sites on different domain not be affected by the
cache? When this happens with me IceCat simply does not open
*anything*. Entirely fresh lookups fail.
But I guess just testing the cache clearing solution could easily prove
or disprove the theory. If it really is DNS cache related, then
someone should probably write a bug report upstream.
