navigator.clipboard.readText() is not working in Firefox

Issue

I have this code for paste:

navigator.clipboard.readText().then(
  clipText => document.querySelector("#Note").innerText += clipText);

But It has this error:

Uncaught TypeError: navigator.clipboard.readText is not a function

help me to solve this bug

Solution

I'm guessing you are testing it in Firefox, in that case:

Firefox only supports reading the clipboard in browser extensions, using the "clipboardRead" extension permission.
