Notes:

document.execCommand('paste') doesn't work on Firefox.
|
|
This may be a bug: https://bugzilla.mozilla.org/show_bug.cgi?id=1603985
|
|
Therefore, navigator.clipboard.readText() is used on Firefox.
|
|
|
|
navigator.clipboard.readText() can't be used in Chrome for two reasons:
|
|
* Requires page to be focused, else it rejects with an exception.
|
|
* When the page is focused, Chrome will request clipboard permission, despite already
|
|
being an extension with clipboard permissions. It effectively asks for the
|
|
non-extension permission for clipboard access.
