exclude extensions from update search?

I think the update is governed by the <em:updateURL>
tag in the install
resource descriptor file.

e.g. <em:updateURL>http://www.foo.com/bar/update.rdf</em:updateURL>

If you can manually remove this tag from the packaged app,
and re pack
and re-install the extension, I think it should no longer
look for
updates.

The packaging is pretty simple, and you should be able to
open the
contents in Winzip or similar utilities.

Hope this helps. 

Thanks, Nandha. I knew those update URL's were buried
somewhere - I
just didn't know where to look.

I actually edited my extensions.rdf file (instead of editing
the
individual install.rdf's and re-installing), deleting the
tags you
mentioned. 

No more update error msgs!

thanks,
