Steps to reproduce the problem:
1. Open a website which prompts malicious popups that have no X button but only an OK button that executes malicious code, practically giving you no options to decline.
2. Now open "Chrome" menu and notice the "Quit Google Chrome" option is grayed out giving you no options but to answer the malicious popup.
3. Also notice that you cannot click the Tab's X button.
4. Workaround is to KILL the chrome process
5. Bam Chrome Big Time Fail.

What is the expected behavior?
You should be able to at least decline the popup, or have an X button on the popup or be able to close the tab or be able to close the entire program. That's just how user friendly software should be.

What went wrong?
Big time fail. On windows version of Chrome, you can at least tick a "prevent popup" checkbox and then click the X button of the popup, and then after a popup comes again, you can actually close the Tab.
