Why does Firefox 4 not load FCKEditor inline editor for Plone 3.x?

Firefox 3.x loads FCKEditor inline editor fine when we use Plone content management system. Since upgrading to FF v 4, the editor will not load.

Would you mind testing whether this problem is caused by the new HTML5 rendering engine?

In a new blank tab...

(1) Type or paste about:config in the address bar and press Enter. Click the button promising to be careful.

(2) In the filter box, type or paste html5 and pause while the list is filtered

(3) Double-click html5.parser.enable to toggle it to false (it should turn bold).

Then return to the page with the editor and reload. If that works, there may be a problem in the editor code or a bug in Firefox. Finding the root cause likely will take more digging...

And if that does not work?

If that doesn't work, can you link to a site that uses the editor so someone can do a hands-on analysis?

I set the preference name 'htm5.parser.enable' to false but fckeditor is not loading on my site. Here is the URL to my forum site that is having this issue:

You will see that there is a large area of white-space after the label 'Forum Post Signature' and this is where the fckeditor should be visible to the user.

When I load that page, I get a series of errors. I think they might all stem from this first one:


Error: Permission denied for <http://forums.chef2chef.net> to get property HTMLIFrameElement.width
Source File: http://forums.chef2chef.net/plugins/fckeditor/editor/js/fckeditorcode_gecko.js
Line: 31

(Line 31 is about 2 screens long...)

Since your script file is version 2.6.3 from 2008, you could try updating: http://ckeditor.com/download (see "FCKeditor 2.6.6, released on 15 February 2010"). Does that make any difference?

Actually, that versions has problems as well. See these discussions of workarounds:
