I moved this thread to the iOS 7 forum as this is what the Crash issue is related to. That said, there are thousands of people including myself with this exact issue. I don't believe the number of tabs open has anything to do with this as I've only one tab open at a time and still had Safari crash on my new iPad Air and iPhone 5S. There are a number of suggestions out there to fix this like; resetting network settings, clear cookies and data, and restoring the device and setting it up as new. However, I have done all of these with my iPad Air and Safari still crashed. I'm currently using the Chrome browser and haven't had it crash since a week ago. This seems to be a far more stable browser for iOS 7 than Apples own Safari, which is sad.... Good news is that I've been reading that the Crash issue has been resolved for a lot of people running the iOS 7.1 beta 2 update.
