Be as informative as you can. I reported it.
I just searched the same keywords but I don't see that phishing site, so maybe it was already removed:
Yeah, I think it was removed about 30 minutes ago. It doesn't seem to show up in my search results now. Firefox also started displaying a warning message which wasn't there before too. It's weird how all of this happened just an hour after I discovered it. Perhaps someone down over at Google or Mozilla headquarters is reading this thread right now.
