Introduction

To protect users' private information, unprivileged scripts cannot invoke the Cut, Copy, and Paste commands in the Mozilla rich text editor, so the corresponding buttons on the dojo Editor2 widget will not work. To enable these functions for purposes of the demo, you must modify your browser preferences.

Configure Firefox

1. Quit Firefox. If you have Quick Launch running (in Windows, an icon in the toolbar), quit that too.
2. Find your Firefox profile directory. On Windows, this is often located in

   C:\Documents and Settings\<Windows login>\Application Data\Mozilla\Firefox\Profiles\<one folder>.
   (See also editing configuration files for more info on locating your profile folder.)

3. Open the user.js file from that directory in a text editor. If there's no user.js file, create one.

4. Add these lines to user.js:

   user_pref("capability.policy.policynames", "allowclipboard");
   user_pref("capability.policy.allowclipboard.sites", "http://localhost file:// http://dojotoolkit.org");
   user_pref("capability.policy.allowclipboard.Clipboard.cutcopy", "allAccess");
   user_pref("capability.policy.allowclipboard.Clipboard.paste", "allAccess");

   *Change the value of capability.policy.allowclipboard.sites to where you want to enable this function. In the example above, this function is enabled for localhost, accessing local files directly (in your own hard drive, without a http server) and dojo website.
   

5. Save the file, and restart Firefox. The Clipboard buttons should now function.

Note: The preference is site as well as protocol specific. For example

user_pref("capability.policy.allowclipboard.sites", "http://dojotoolkit.org")

user_pref("capability.policy.allowclipboard.sites", "https://dojotoolkit.org")
