Please remove this sound... thanks :) Reproducible: Always Steps to Reproduce: 1. Type in a site's name, like "yahoo" or "google" or "mozilla" 2. Press COMMAND + RETURN. 3. The URL will turn into http://www.yahoo.com (as it should), but it will also make an annoying prompt sound (which it should not).
