Try this in non-IE browsers:
alert( window.clipboardData )
You will most likely get 'undefined'. Firefox et al don't support
copying to the clipboard.

So, I need to detect those browsers and disable the clipboard options?

Take a look at
I would like to respectfully disagree with RobG.
I think that Firefox does support clipboard operations (as did
Mozilla), through XPConnect as you note.
Your "if" statements should also discount other browsers, as you
correctly do this by means of a "feature" test.
I would think that your problem lies somewhere in your XPConnect code
stated above. I have not had chance to look closely, but XUL Planet is
a good source of information.

Please don't top-post. Although that is the default behaviour of
Outlook Express, but it's not the preferred layout of this group.
Here are a couple of links regarding using the clipboard and Mozilla:
<URL:http://www.infogears.com/cgi-bin/infogears/mozilla_firefox_copy_paste.html>
<URL:http://www.mozilla.org/projects/security/components/per-file.html>
Users can allow access to the clipboard on a per-site basis, however it
requires modification of user preferences that are likely beyond the
average web surfer. As a result you should expect that, in a general web
context, clipboard support is not available.
If your usage is for an intranet, and you can control a users' settings,
then maybe you can make it work reliably. This newsgroup is intended to
focus on JavaScript for the web, hence responses tend to bent in that
direction.

Yes, I was a bit dismissive. :-x
Mozilla does support the clipboard, but only through specific user
actions to allow access to it. Page authors should not expect clipboard
support to be available, and therefore should probably not attempt to
use it. The links above show how to enable it - I don't think your
average user is going to be able to do it even if you can convince them to.
Support within an intranet may be able to be made more reliable.

The feature tests are insufficient - testing for 'window.netscape' does
not ensure that PrivilegeManager.enablePrivilege is supported, or that
the user will allow the privileges to be modified.
That call should be inside a try..catch block in case the user refuses
to change their privileges, or you can let them deal with the message
starting:
"A script from /your_domain/ is requesting enhanced abilities that
are UNSAFE and could be used to compromise your machine or data:"

Thanks for the very educational response.
I'm not sure what "top posting" is nor how to prevent it?
I'll do some more reading and re-think my general approach here. Too bad
because, in my option, saving the user from having to select and the "copy"
seems like a good thing. It is so easy to accomplish for IE.
Oh well

IOW, readable like black ink on black paper.

Inline and bottom posting are the preferred Newsgroup styles.
You can prevent top posting by trimming the quoted text to the essential,
reply inline (just after a section you want to comment on, answer or reply to)
and/or at the end (or bottom) of the quoted (and hopefully now trimmed) text
like I am doing right now.
