Why does the Browser seem to snapshot the page I'm on

For some reason when I access a new web page the browser places a transparent dark screen over the page for a few seconds. It seems to be taking a snapshot. It makes me wonder if you are taking pictures of the sites I’m browsing.

I am a conservative. Are you part of the anti-American cartel in Hi Tech that is in the process of destroying free speech, indeed freedom in America today? If you are I have no use for you.

I will admit one thing though, the browser is incredibly fast compared to others.
