User-Agent: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.5) Gecko/20031007 Firebird/0.7 Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.5) Gecko/20031007 Firebird/0.7 Firebird appears to do a google "I'm feeling lucky" query when the host does not respond, or is not found. To get a simple idea why this is a very bad idea, try http://localhost:8080 If you are not running a web server on that port, you end up viewing some random internet marketing site. Note that this forwarding occurs even if localhost is your home page, and the stop button seems to be disabled during the query, so you are going there, whether you want to or not. Why this is bad: 1) It turns firebird into adware. Who wants to get a random porn or spam site, if that is what corresponds to a google query with the name you typed. 2) It takes you to the wrong places. Host names != keywords. if you wanted http://somewhere.com, and type http://somewhere, you probably won't end up at somewhere.com. 3) It's very confusing. The URL you typed is gone, and silently replaced by some unrecognized, and probably unrelated url. 4) You don't seem to be able to cancel it, since the stop button is greyed. If this mis-feature is going to be included at all, then at least a check box to disable is critical (and clearly should default to "don't do it"). Think about the reaction to verisign's site finder service, which did basically the same thing (though from different motives.) Reproducible: Always Steps to Reproduce: 1. make sure you are not running a web server on port 9090 2. type http://localhost:9090 into firebird. 3. note that you end up at http://www.netbreakthroughs.com/ Actual Results: you end up at http://www.netbreakthroughs.com/ , rather than the host you expected. Expected Results: If the host is not found, display "host not found". Do not substitute other hosts.

Kinda like bug 171495, but different. If you want to (sort of) turn it off, you can try this http://texturizer.net/firebird/tips.html#beh_search

REOPEN: Firebird is going to get a couple IK bugs, which will be marked as depends to Mozilla bugs. Also, IK is going to get a localhost bug as well.

This is a dup of bug 184433.
