If you are having problems using FCKeditor on Firefox 3.6, it's due to a, lets call it a Year 2010 bug. You will see a textarea instead of the editor. This probably only exists in the ColdFusion version, I haven't checked the other versions...

The useragent for Firefox 3.

I have a client using the standalone FCKEditor on his server (not the one in /CFIDE/ it is located at /FCKeditor/), but after installing the security hotfix for ColdFusion 8's builtin FCKeditor, the file manager for uploading and inserting images stopped working.

Adobe has just released a security hotfix for the FCKeditor vulnerability in Coldfusion 8.

Also of Note, Adobe's Terry Ryan posted a blog entry today detailing How to report a ColdFusion Security Issue to Adobe.

I've had a chance to look at the FCKeditor code a little bit in order to determine what the risks actually are of this vulnerability.

There have been a few stories about a vulnerability in FCKeditor that is bundled with ColdFusion 8, first on SANS and now on The Register.

The FCKeditor ColdFusion connector isn't enabled on all CF installations, I think if you installed a fresh 8.0.
