Review for AutoCopy by Ped7G
Rated 5 out of 5 stars
I love this behavior for more than 15 years now, thank you to bringing it into ff[3b5 now too! *yay, thanks!*] on windows too, I was missing it there many times.
I just don't understand why this is not default (or at least option in some) in every OS, it feels so natural to me.
