CKEditor 4.0 on Wordpress 3.5 and Firefox

[davidw93]

When running any CKEditor 4.0 release on Wordpress v3.5 the editor does not show in Firefox. The editor loads in both Chrome and IE however fails to display on Firefox.

Both errors are thrown by scayt Developer console displays error relating to _base.xd.js as an empty string is being passed into getElementById(): var _3db=document.getElementById(_3da);

caused by: var _3da=t.containerNode.parentNode.getAttribute("widgetid");

Errors also thrown by loaderbase.js:

getAttributeNode is deprecated and should be getAttribute var attr=node.getAttributeNode&&node.getAttributeNode(_349);

attr.specified is deprecated and will always return true return attr?attr.specified:false;

This issue is very similar to #9504.

There are some methods that were deprecated in Firefox (starting from Gecko 7) and have to be changed. These errors popup in SCAYT code and not core files of CKEditor.

I was unable to reproduce this error (FF 17.0.1 @ Win 7), I mean the editor shows up properly. Are you still having this problem? Can you clear browser cache?

1. Are you using CKEditor (the editor) that comes with CKEditor 4.0 for WordPress, or did you replace "ckeditor" (wp-content\plugins\ckeditor-for-wordpress\ckeditor) folder with your custom build?

2. What are your "Advanced Settings" in WP?
   • SCAYT auto startup. YES/NO ?
   • Enable the built-in spell checker while typing natively available in the browser. YES/NO ?
   • Plugin: Spell Check As You Type (SCAYT) YES/NO ?
   • Plugin: WebSpellChecker (WSC) YES/NO ?

3. Can you try reproducing it on a vanilla installation of WordPress, to exclude issues caused by 3rd party extensions etc.?
