I have External Editor (zopeedit-win32-0.9.3.exe) installed on my WinXP machine.  It works fine with my IE6 browser.  But with Firefox 2.0, it doesn’t. 

Specifically, with the ZMI running in Firefox, what happens is:

1. I get the stubby pencil icons on editable Zope objects.
2. Clicking on the stubby pencils brings up that page in my selected external editor (currently Dreamweaver, but I have tried this with other tools and the results are the same).  So far, so good.
3. But when I save changes from the external editor, the changes don’t make it back into Zope, and they don’t show up on the rendered pages. 
1. The changes do show up in the temp file that the external editor saves to.  So the problem is not with the external editor’s file saving abilities.
2. No error messages occur. 
3. So the problem must be that the EE helper app is not picking up the changes, or is not getting them back to Firefox.

My hunch is that I have failed to execute the following step in the IE Windows installation instructions (http://www.plope.com/software/ExternalEditor/install-win32):  “You can also register it (zopeedit.exe) with other browsers directly.”  The reason I haven’t done this step is that I can't find out how to register a helper app in Firefox.  And after a lot of Googling etc, I’m still stuck.

The only clue (or not) I have to offer is that the file “C:\Documents and Settings\Ken\Application Data\Mozilla\Firefox\Profiles\uhpuzmf9.default\mimeTypes.rdf”, which apparently is the operative Firefox configuration file, has these relevant (or not) entries:

<RDF:Description RDF:about="urn:mimetype:externalApplication:application/x-zope-edit"

                   NC:path="C:\Program Files\Macromedia\Dreamweaver MX\Dreamweaver.exe"
