Github user AhyoungRyu commented on the issue: https://github.com/apache/zeppelin/pull/1750 @felixcheung Yeah you're right. So I changed the library from `angular-zeroclipboard` to [ngclipboard](https://github.com/sachinchoolur/ngclipboard/) which is not using flash. It says >Angularjs directive for [clipboard.js](https://clipboardjs.com/). A modern approach to copy text to clipboard without using flash. And I checked it works well in `Chrome` / `Firefox` / `Safari`. Thanks for letting me know :)
