For example, if I enter http://localhost:9000 and a server is not listening on that port, I am redirected to http://www.localhost.net.au/. I thought this might be feature and looked in options and couldn't find anything that seems related to this 'feature'. I tried in Mozilla 1.6 and IE and can not reproduce on those browsers. Reproducible: Always Steps to Reproduce: 1.Enter http://localhost:[some port] 2. 3. Actual Results: If a server is not running on local host, redirected to other web pages Expected Results: Show a host not found page or page can not displayed message.

This is a known bug. It was fixed before Firefox 0.8 was released, but because 0.8 was the result of work at fixing problems on a copy of the source code made before that (and pretty much *only* fixing problems - very few new features or risky bug fixes, only urgent problems that required immediate attention), 0.8 doesn't have this fix. Firefox 0.9 will work correctly, as will any of the recent Firefox nightlies if you're inclined to test one out. Recent nightlies have been relatively stable as long as you don't attempt to import old settings using Firefox itself, but your mileage may vary. *** This bug has been marked as a duplicate of 184433 ***

V/dupe. Reopen if this is happening w/ 0.9

BTW, "host not found" usually means that the name doesn't exist in DNS. In your case, your system did not answer for that port, that is a different error.
