Steps to reproduce the problem:
Google add big regression since it autorise fullscreen without permission. and never add a real popup blocker.

browse this: http://www.support.microsoft770571yfrmsrbchs9670.com.s3-website.eu-central-1.amazonaws.com/index.html

What is the expected behavior?
request to add site to exception list for FULLSCREEN,
and block all popup.
not analyse how it can disturb mouse (high cpu,graphics..)

What went wrong?
site enter fullscreen, read MP3 to call one phone number.
If not clic immediatly to ESC and close (example, search to copy URL to report this badpage @amazonaws ..)
Press ESC can't access to menu to close tab. one tiny popup stay in bottom righ (see it with more website now; it can open new fullscreen page after more second)
very difficult to clic in tab to close, not respond, and popup appear to close. Hard to go in the popup, mouse hang...

How many use call number? because can't close it, or not see must press ESC to exitfullscreen ?
to believe that Google encourages this practice by allowing the passage in full screen

Did this work before? Yes

Why not just enable again the list exception for fullscreen, perhaps prefilled (google.com,youtube,...).
and same to block popup (all popup)or open all popup in new tab.
