However, the behavior of Firefox in resolving URL's is still strange! If I click on a link, firefox spends almost a full minute to resolve the url, so while it is waiting (spinning), I use the gnome terminal to nslookup whatever-domain-it-was.com and it resolves it in less than a second. I look at firefox, and it is still trying to resolve!! Firefox seems to use some other way to resolve the url's domain - the painfully slow way!! Firefox has no config means of telling it how to resolve - so I'm at a loss as to it's behavior.
