I just verified this on firefox (2.0.0.3+1-0ubuntu2) and the behaviour is the same, using a clean profile with and without safe mode.
In a clean profile type "query" into the address bar, you will be redirected to <http://en.wikipedia.org/wiki/Query> Now go to the proxy settings, and setup a proxy for HTTP and repeat. You are sent to <http://query/> I have used both Squid and Tinyproxy to test this, Tinyproxy log appears to show that Firefox doesn't even talk to google: CONNECT Apr 19 14:57:00 [17950]: Connect (file descriptor 7): ktulu [192.168.0.3] CONNECT Apr 19 14:57:00 [17950]: Request (file descriptor 7): GET http://query/ HTTP/1.1 INFO Apr 19 14:57:00 [17950]: No proxy for query ERROR Apr 19 14:57:00 [17950]: opensock: Could not lookup address "query".
