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.

muito bom e uma exrtencion de qualidade

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