Cut,copy And Paste Is Not Working For Firefox 15 Onwords?

I am using the netscape.security.PrivilegeManager.enablePrivilege('UniversalXPConnect') for firefox. i am facing the problem for browser compatability for editor. we are using HTML

Solution 1:

From Mozilla's support pages;

Starting in Firefox 17 privileged code can not run in a web page anymore. In Firefox 15 you have to manually change a setting to enable it. You can bring that kind of functionality to an extension. Starting points: https://developer.mozilla.org/en-US/docs/Code_snippets/Interaction_between_privileged_and_non-privileged_pages

Here you can find a (somewhat heated) discussion on the subject that has been going on for a couple of years :)

Solution 2:

I recommend ZeroClipboard as a workaround. You can select an element by ID and overlay it with a transparent flash video of the same size. Flash allows access to the clipboard so you can cut/copy things. If iThings aren't so much of a worry, it might be a decent option.

ZeroClipboard requires Flash version 9 or higher. So I would use swfobject to check for the required version first.

if (swfobject.hasFlashPlayerVersion('9')) {
    $.getScript('/js/ZeroClipboard.min.js', function(){
         ZeroClipboard.setMoviePath('/swf/ZeroClipboard10.swf');
         var clip = newZeroClipboard.Client;
         clip.setCSSEffects(true);
         clip.setHandCursor(true);
         clip.glue('copy-elem-id', 'copy-elem-id-container');
         clip.addEventListener('onMouseDown', function(e){
             var copyText = $('#textbox-id').text();
             clip.setText(copyText);
         });
    });
}

Solution 3:

we need to add some privileges using about:config with out quotation.

user_pref("capability.policy.policynames", "allowclipboard"); user_pref("capability.policy.allowclipboard.sites", "https://www.mozilla.org"); user_pref("capability.policy.allowclipboard.Clipboard.cutcopy", "allAccess"); user_pref("capability.policy.allowclipboard.Clipboard.paste", "allAccess");
