Do not visit crashsafari.com on an iPhone. It will crash your browser or even the device itself.
Because we are foolish care about our readers, we tried this and can confirm that the website will indeed crash an iPhone 6S and an iPhone 5S running iOS version 9.2.1 and a regular iPhone 6 running iOS 9.2. In other words, if you're using a recent iPhone or one running the latest version of iOS, you're probably at risk.
When you visit the website, it'll load for a moment and then crash Safari or force a reboot of your iPhone, sending you back to the home screen with everything else intact. Depending on your settings, you might lose some tabs, but it won't do anything to damage your device otherwise.
We also tried accessing crashsafari.com using the Chrome browser on the Samsung S6 Android phone. The phone didn't crash, but the website did freeze the app, making it impossible to go to a different URL. That said, we were able to minimize and close the app as normal.
People have reportedly been sharing the link on social media and sending it to friends using link shorteners to trick them into opening it. But you wouldn't do anything so vile, would you?
