thank you :D

Does exactly what you want it to, no extra clutter! A button that mirrors the webpage. Perfect, thank you.

Fantastic! Simple, straight-forward click-and-fix solution. Great for watching videos that have mirrored themselves to avoid excessive copyright claims (a problem that has plagued YouTube forever).

Precisely what I was looking for. Don't know why I didn't check out extensions first, because Googling how to reverse your Windows 10 screen? Not fun. You will never get an answer that way.

This is perfect for watching Youtube videos that have been mirrored, thanks! :)

simply mirrors the page rendering... for instance use with http://www.bl.uk/manuscripts/Viewer.aspx?ref=arundel_ms_263_f018v
