I also experience this and can't pinpoint what's causing it yet. I have around 14 tabs open, GMail, Whatsapp and mostly forum sites. I don't recall experiencing this before the update. I have HW acceleration turned off since before the update. The crash occurs at random, sometimes 15 min after starting. sometimes it can run for hours before it crash. Sure it autostart right back, but it's annoying to say the least, not to mention losing all I've typed in a forum reply :(. I hope this will gets identified and fixed soon.
