I am trying this small piece of code:

<textarea onselect="document.execCommand('copy');">Hello I'm some text</textarea>

It seems to work for Chrome but not for firefox. Does firefox not provide a functionality for copying contents to clipboard. I fyes, what are they because I am definately missing them.

I am getting this error on Browser console: 20:43:49.409 NS_ERROR_FAILURE: 1 try1.html:1:0

Any solutions for copying text to clipboard from firefox browsers?

Hi bansal5575, did you follow the link to the bug tracking system? It is scheduled to appear in Firefox 41, which is about 8-9 weeks away from release.

https://developer.mozilla.org/Firefox/Releases/41#InterfacesAPIsDOM

You can test Firefox 41 in its current early form to see whether it meets your needs: https://www.mozilla.org/firefox/developer/

You probably should make a backup of your Firefox profile first. This article has tips on that: Back up and restore information in Firefox profiles.

Firefox doesn't allow access to the clipboard via scripts. Use keyboard shortcuts if the buttons on the web page or other methods aren't working.

  • Copy: Ctrl+C or Ctrl+Insert (Mac: Command + C)
  • Paste: Ctrl+V or Shift+Insert (Mac: Command + V)
  • Cut: Ctrl+X or Shift+Delete (Mac: Command + X)

When Google Chrome seems to be providing a solution for this, why is there no support in firefox? This use case is a very important feature for one of the apps that I am developing and users won't be pleased having this feature only in chrome and not in firefox.
