DO NOT CLICK THE LINK! Hour later I am still unable to restart my phone. It hangs on logo!! This may be a permanent fuck ;( unsure exact version but I have iOS 7 that hasnt been updated in about six months.
If you use iCloud for Safari, you can close another device's Safari tab from your Mac. click the iCloud tabs icon on desktop Safari, then click the circle-x to close the offending tab.
Seems like on restart Safari wants to revisit previously opened pages and crashes again ad infinitum. Isn't there a way to cold-restart iOS devices or some such (like the magic "Zap NVRAM and repair permissions" procedure back in PowerMac times)?
I'm sure you're in the absolute minority. Most people want all apps, including the browser, to stay the way they were when they closed them, even after a reboot
