 Nice idea. But I think it needs revision due to usability issues. See the
 attached screenshot for an example: This is a maximized window where
 essentially 1/3 of the browser window is grey and unusable despite the
 user wanting to have the maximum browser window possible on her screen.
 Similar things happen in fullscreen mode, e.g. I think denying the user to
 give her Tor Browser in fullscreen/maximized mode is just leading to
 frustration and switching to a different browser.

 The challenge here has never been to enforce rounding of a window by a
 certain multiple of, say 100. The challenge is to achieve that AND don't
 change how the browser looks like or behaves in important ways. I think a
 viable improvement would at least be if we would prompt a user *before*
 the window is actually maximized/in fullscreen mode (#7255) which we'd
 need anyway even if we don't take this patch but just make the user aware
 that she is about to shoot herself in the foot. And, yes, zooming (#7256)
 is an interesting approach which might get us around all of the rounding
