This autocopy is the smartest Noté 5 sur 5 étoiles
It allows text replacing in writable fields unlike other addons - let assume I need to replace some text, by another one, that just copied into clipboard. This addon allows me to select the replaced text and replace it by copied with Ctrl-V or Paste.
Other autocopy addons copy the replacing text, overriding just copied into the clipboard that extrimely undesired.
So, the reason, that this addon doesn't autocopy text from writable fields is more then justified - this is fully right behavior.
