Style Sheet Parser JavaScript Error in Firefox

[raymondp413]

The style sheet parser example page produces a JavaScript error in Firefox.

The example page is here: ​http://nightly.ckeditor.com/latest/ckeditor/_samples/stylesheetparser.html.

The error is: Error: uncaught exception: [Exception... "A parameter or an operation is not supported by the underlying object" code: "15" nsresult: "0x8053000f (NS_ERROR_DOM_INVALID_ACCESS_ERR)" location: "​http://nightly.ckeditor.com/latest/ckeditor/plugins/stylesheetparser/plugin.js?t=C0B85O7 Line: 6"]

Firefox Version: 8.0.1

OS Version: Snow Leopard

To reproduce just open stylesheetparser sample. You will notice error in console.

Issue is reproducible in All browsers.

Version: Ticket reproducible from rev [6904] (CKEditor 3.6) but if you check release versions you will only notice this error in CKEditor 3.6.2 (and this is the version I'm setting).

In Firefox:
Message: A parameter or an operation is not supported by the underlying object" code: "15
URI: /3.6.2/ckeditor/plugins/stylesheetparser/plugin.js?t=B8DJ5M3
Line: 6

In IE:
