Every once in a while when installing an extension, the entry that shows up
while it's downloading doesn't go away when done, leaving an entry like the
following in Extensions.rdf:

  <RDF:Seq RDF:about="urn:mozilla:extension:root">
    <RDF:li RDF:resource="file:///C:/tabextensions_en.xpi"/>
    ...
  </RDF:Seq>

did you close the EM window while the extension was downloading?
can you still reproduce the problem?

Comment 2

[Ron Baldwin]

No, I didn't close the EM window while they were installing.  I also haven't
found a way to cause it every time.

It seems that this is part of a larger problem with the EM.  For example, with
1.0 final, I dragged multiple xpi files from explorer to the EM window.  Once it
was finished installing, each one showed up twice, once for the "real" entry and
once for the "fake" entry consisting of just the extension's file name.  Each
one also showed up in the DM as a download in progress.  When I closed Fx, it
asked me to cancel all of the downloads (even though they were never downloaded,
and even though they were done installing).  In this case, when I restarted the
"fake" entries were gone from the EM.

Note that even though this last problem occurred when installing from the local
drive, my original problem occurred when installing from a web site.

I see this bug too, for example with an update of flashgot to 0.5.9.98 the following was added/altered in extensions.rdf

should not be there. And when deleted the dead entry disappears.

Same problem for me. Happens after upgrading from RC2 to 1.5 final. Removing extensions leaves dead entries behind. I've checked extensions.rdf and cannot confirm left-over entries. The extensions in question are not referenced in extensions.rdf.

Any news on this one? Still keep getting dead extensions when upgrading to later version.

Thanks,
Andi

You should probably track one of the same bugs that were reported for Firefox 1.5 like bug 319022 or bug 318926 and not this one.

The cause of this occurring with 1.5 is known and the symptom can be fixed by deleting the extensions.rdf in the profile directory... it will be regenerated on restart which is new with Firefox 1.5.

The patch in bug 319022 resolves what I believe is the worst case of this occurrence though there is at least one other relating to closing the app and the cancel download prompt not removing the download item from the rdf and there is another bug for that specific issue.
