At 
http://lxr.mozilla.org/seamonkey/source/modules/libpref/src/init/all.js#456
pref("capability.policy.allowclipboard.sites", "http://www.mozilla.org");

So to use this in your own application you would need to enable 
security... try one of the following:
netscape.security.PrivilegeManager.enablePrivilege("UniversalBrowserRead"); 
(this might work for copy)
netscape.security.PrivilegeManager.enablePrivilege("UniversalBrowserWrite");
(this might work for cut/paste)
netscape.security.PrivilegeManager.enablePrivilege("UniversalXPConnect");
(this might just work)

If you're doing this from website JS (as opposed to the local 
filesystem), you will need a signed script.
