I tried like 10 different copy and paste extensions and this is the ONLY one that both worked AND didn't come with ads. (Most of them don't actually work ;-;)
10/10 recommend.

good in Android. add words: unblock Text Copy protection in info.

It works! Tested on a Copy & Right-click context menu disabled Google Spreadsheet.

it's really great add-on!

Does what it says.
