Why Is My iPhone Stuck On iOS-crash-report.com? Here's What To Do.
That is 100% NOT an Apple website. You need to go to Safari and click Settings -> Safari -> Clear History and Website Data. You got a bad cookie while searching and you need to get rid of it. It will continue to pop this up until you clear it out.
If this happens again, force close Safari immediately and clear website data. I know it is not from Apple because ALL Apple websites have Apple.com in them, including all support pages, with a few exceptions like iCloud.com.
