402977 - code to close windows that launched downloads doesn't work if that window's opener closes itself

Status: NEW

(Firefox :: File Handling, defect)

Description

See discussion and testcase in bug 355222.

Quick summary: The IBM download site uses two windows to initiate a download. One to select the kind of file, which then launches a new window with the URL of the file that then closes itself. Previous to the patch for  bug 355222 that would fail, so as a quick fix we disabled the code that would attempt to close the window used for download, so that we could use it as a context to pass to nsIHelperAppLauncherDialog::show.

Instead, we should probably try to do something better, like closing it and using it's parent as the context. We didn't take this solution in that bug because I am worried that we'll have no way to ensure that it's parent is actually related (from a user's perspective) to the window that actually triggered the download.
