 Replying to [comment:9 gk]:
 > Yeah, I just made a nightly build forgetting about the different certs,
 good. While the updated/ directory is gone there is now the problem that
 every start produces the check-your-extensions-compatibility-dialog which
 is quite annoying. This does not happen without using your updater.exe and
 we should avoid that.

 I do not see how the fix for this ticket could affect the extensions
 compatibility dialog.  How can I reproduce that problem?  Is it a dialog
 that stays open or is it the one that quickly opens and closes while
 checking for extension updates? (maybe I do not see it on my system
 because it closes too quickly)


 > Btw: Do you know where this mysterious `tobedeleted` directory is coming
 from with weird "temporary files" in it (happens without your updater.exe
 as well)? I just saw this inside /Browser after the update while testing.

 Having a few files in "tobedeleted" is expected.  If the updater is unable
 to delete a file on Windows because it is in use, it moves the file to a
 tobedeleted directory and arranges for the file to be deleted the next
 time Windows is restarted.  The file is also renamed to so it has a
 temporary/unique name.  This usually happens for updater.exe and the
 NSPR/NSS DLLs.  While describing this to you, I just realized that this
 involves Windows registry changes.  Should we create our own code to clean
 up the "tobedeleted" files?
