(Answer) (Category) WebGUI FAQ : (Category) Sticky/News/Non Sequitur :
Copy/Paste Mozilla/Firefox
It took me a long time to figure out how to do it, and sometimes RTFM DOES work :) heh heh...
The point: Can't paste into HTML Area3 from Firefox because of security.
The solution: find your prefs.js location. In Windows, it is located in your user profile, Application Data\Mozilla\Firefox\Profiles\SoMeRaNdOmStRiNg
create user.js or modify existing user.js
Add these lines (note that the sites line is a space separated list of sites): 
 user_pref("capability.policy.policynames", "allowclipboard");
 user_pref("capability.policy.allowclipboard.sites", "http://demo.plainblack.com http://www.plainblack.com");
 user_pref("capability.policy.allowclipboard.Clipboard.cutcopy", "allAccess");
 user_pref("capability.policy.allowclipboard.Clipboard.paste", "allAccess");
