mozilla adds .com to bare words when typed in the location field. I can that this could be useful, but it can have a negative effect. I just typed googlecom (note missing dot) into the location, and mozilla expanded to a googlecom.com which is a PORN site which frames and includes google.com, plus puts up lots of those damn popups. NOTE : DO NOT TRY THIS YOURSELF! THESE GUYS LOVE THE EXTRA TRAFFIC! In this case it was a little more than annoying, especially since I though I was at the real google. It can of course have a significant security impact, if the spoofed example was a bank or some other site.

i think this note about the security issue is something to think about, but this is a dupe of bug 115539
