Firefox and Safari on the iPhone can now report your physical location. But who are they telling
Allowing your Web browser to determine your physical location opens the door to some seriously nifty features. Some iPhone apps (such as Yelp for iPhone) can help you find nearby restaurants, bookstores, or other places within walking distance, for example. But such functionality, available in the newest Firefox and in Safari on the iPhone, also opens the door to some serious privacy concerns: Where you physically sit or stand at any given moment is deeply personal information that you don't want to give to just any site. I tried the new features to see how the browsers handle such privacy concerns.
