This code works fine in Google Chrome, Opera, IE 11. But it doesn't work in Mozilla firefox and Safari. I get error in the following string "var successful = document.execCommand('copy');"

- From mdn : "copy Copies the current selection to the clipboard. For Mozilla, clipboard capability must be enabled in the user.js preference file. See A brief guide to Mozilla preferences for more information." – Kaiido Commented May 6, 2015 at 14:08
- @Kaiido this solution doesn't work. Firefox version 37.0.2 – Vadim Denisuk Commented May 6, 2015 at 14:32
- did you follow those steps ? (didn't tried myself) – Kaiido Commented May 6, 2015 at 14:47
- Also always though that this answer was the best solution : stackoverflow./a/6055620/3702797 I would hate your website so much if because of some action I wasn't aware, I do loose all the content I kept in my Clipboard – Kaiido Commented May 6, 2015 at 15:00
- 1 @Kaiido According to bugzilla.mozilla/show_bug.cgi?id=913734 , capability.policy.* preferences have been removed since firefox 29. The documentation is not up to date. – 林果皞 Commented May 8, 2015 at 8:43

Reset to default 5As of Firefox 41 (September 2015) the copy mand should be available by default when triggered from certain trusted (user-triggered) events, such as what would be fired in response to a button click. The patibility table from MDN offers further information, see also the release notes.
The code in the question should therefore work. Indeed, I tested something very similar (see code below) and it worked great for me using Firefox 44.
function doCopy() {
var textToCopy = document.getElementById('textToCopy');
var range = document.createRange();
range.selectNodeContents(textToCopy);
window.getSelection().addRange(range);
document.execCommand('copy');
}
(function() {
var el = document.getElementById("copyTrigger");
el.addEventListener("click", doCopy, false);
})();textarea {display: block; margin-top: 1em; width: 500px;}<div id="textToCopy">Elephant</div>
<button id="copyTrigger">Copy above text</button>
