On a single computer in our network, the cftextarea is not rendering properly in Firefox 41.0.2. The Firebug console displays errors only on that specific computer;
SyntaxError: missing } after function body fckeditorcode_gecko.js:108:329
ReferenceError: FCKConfig is not defined fckconfig.js:27:1
ReferenceError: FCKBrowserInfo is not defined fckeditor.html:125:1
ReferenceError: FCKConfig_LoadPageConfig is not defined fckeditor.html:164:1
ReferenceError: FCKTools is not defined fckeditor.html:176:5

ReferenceError: FCKLang is not defined fckeditor.html:203:1
ReferenceError: FCKBrowserInfo is not defined fckeditor.html:270:1
ReferenceError: InitializeAPI is not defined
This issue does not occur on other computers using Windows 7.
I am unsure of what could be causing this problem!
UPDATE:
When navigating through a list of emails to send out in a specific application, I encounter a blank textarea after about three records. If I hold down the shift key and click the refresh icon in the URL bar, the textarea disappears completely. There seems to be some sort of placeholder as the area for the textarea remains blank. Subsequently, all textareas on any other page also appear blank. It almost feels like a virus spreading throughout the system.
