Have the same problem as pedro2mp describe, and can't find any solution...>
I have an extension called Gmail Notifier Plus and every time I receive a message (should make a sound and show a desktop notification popup for new emails), the browser closes and then opens automatically and then after 2 seconds (when supposedly should make a sound again and show the pop because I didn't read the message) it crashes again, closes and opens. This happens a few times until the browsers just closes and never opens automatically again. I also noticed that when this happens, sometimes, the browser initiates without the extensions activated (I assume it is to protect the user in case something like the problem I have happens). I've tried both Gmail Notifier and Gmail Notifer Plus and they both have the same problem. This started happening since 2 versions ago, I'm not sure if the problem is in the new versions or the windows 10.
