Crashes from time to time

The Chrome app crashes sometimes out of nowhere. Very annoying. And it seems like the button/feature that enables you to zoom out and see all the webpages that are open as you can do in Safari, is gone? I was just using it earlier yesterday, then it seemed like it disappeared? Please fix this problem. And block ups pop up using certain websites, even though I have the "no block-ups" tab switched to work.
