I find this to be highly inconsistent. Sometimes the videos are in expanded view, sometimes in default view, sometimes in cinema view and sometimes in theater view, all without changing the settings in this extension. Makes it highly unpredictable as to what my viewing experience will be.

On top of that, the settings are very obtuse in what they actually do and how thee interact with each other. For example, I count at least three different settings for the viewport size. WHY???
