Hello,
Assume a browser extension has a “copy code” button which the user can click on.
If/when the user clicks on the button, it will copy the hidden code to the clipboard and also reveal the code (which the user is expecting) but it will also open a new pop-under tab which will open to special website to earn a commission and then immediately close the tab once the commission has been earned (the user does not know about the pop-under tab).
Basically, is the pop-under tab allowed?
