Safari is crashing for a lot of people due to this odd bug
Though Apple hasn't made an official statement about the issue, many users pointed out that simply turning off Safari suggestions in the browser's settings will fix the problem.
The option can be found under Preferences - Search on desktop Safari. On the iPad and iPhone, both of which appear to be affected, you can find it under Settings - Safari. Turn off the option, and your browser will stop crashing.
The bug doesn't impact all users, but it seems to affect Safari on iOS 8 and 9, as well as the latest version of El Capitan, OS X 10.11.1.
Safari crashing on phone and laptop all morning has been pretty annoying. Thankfully it's fixable by just turning off 'Safari Suggestions'— Christopher Willetts (@cgwilletts) January 27, 2016
If Safari on your Mac is behaving like a muppet since the recent 10.11.3 update, disable Smart Search Field prefs. Wasted an hour there...— Gavin Smith (@gvnsmth) January 27, 2016
