Hello bajaj, That changeset removed closeProgressWindow from the nsIHelperAppLauncher interface. The download manager has a new UI, and there is no longer a progress window. There are no native callers to closeProgressWindow, I can't think of a legitimate reason for an addon to call it, so I don't think it's worth revving the version number. Many addons that touch downloads will have to be modified anyway, and that discussion is going on on firefox-dev. Thanks, Monica
