Firefox 17 - CKEditor 4 - Error: Permission denied to access property 'DEBUG'

[Angel Cervera Claudio]

After upgrade Firefox to 17, CKEditor throws this error:

Error: Permission denied to access property 'DEBUG' [Parar en este error]

debug: window.top.DEBUG

{

/ckeditor/plugins/magicline/plugin.js (línea 33)

In Opera, Safari and Chrome work fine.

Regard.

Could you provide us more details about how you load CKEditor? From other domain maybe?

[Angel Cervera Claudio]

No, I open from same domain. I open a page in a iframe and this page use ckeditor. This is the fragment how activate ckeditor:

The "instanceCreated" event is fired for every editor instance created. CKEDITOR.on( 'instanceCreated', function( event ) {

var editor = event.editor,

element = editor.element;

if ( element.is( 'h1', 'h2', 'h3' ) /*

element.getAttribute( 'id' ) == 'taglist' */ ) {

editor.on( 'configLoaded', function() {

Remove unnecessary plugins to make the editor simpler. editor.config.removePlugins = 'colorbutton,find,flash,font,' +

'forms,iframe,image,newpage,removeformat,scayt,' + 'smiley,specialchar,stylescombo,templates,wsc';

Rearrange the layout of the toolbar. editor.config.toolbarGroups = [

{ name: 'editing', groups: [ 'basicstyles', 'links' ] }, { name: 'undo' }, { name: 'clipboard', groups: [ 'selection', 'clipboard' ] }, { name: 'about' }

];

});

}

});

In this new version, firefox implements sandbox attribute. It's possible that the error it is related with this matter.

I use iframe with sandbox="allow-scripts"

Thanks
