LauncherDialog_Download(

Answer 1

Jonathan's solution doesn't work with geckoFX 45 - it seems they changed some of the libraries and deprecated the download manager. Here is the same event snippet updated to work with GeckoFX 45

    private void LauncherDialog_Download(object sender, Gecko.LauncherDialogEvent e)
    {
        nsILocalFile objTarget = Xpcom.CreateInstance("@mozilla.org/file/local;1");

        using (nsAString tmp = new nsAString(@Environment.GetFolderPath(Environment.SpecialFolder.ApplicationData) + "\temp.tmp"))
        {
            objTarget.InitWithPath(tmp);
        }

        //Save file dialog
        Stream myStream;
        SaveFileDialog saveFileDialog1 = new SaveFileDialog();

        saveFileDialog1.Filter = "All files (*.*)|*.*";
        saveFileDialog1.FilterIndex = 2;
        saveFileDialog1.RestoreDirectory = true;
        saveFileDialog1.FileName = e.Filename;

        if (saveFileDialog1.ShowDialog() == DialogResult.OK)
        {
            if ((myStream = saveFileDialog1.OpenFile()) != null)
            {
                nsIURI source = IOService.CreateNsIUri(e.Url);
                nsIURI dest = IOService.CreateNsIUri(new Uri(@saveFileDialog1.FileName).AbsoluteUri);
                nsAStringBase t = (nsAStringBase)new nsAString(System.IO.Path.GetFileName(@saveFileDialog1.FileName));

                nsIWebBrowserPersist persist = Xpcom.CreateInstance("@mozilla.org/embedding/browser/nsWebBrowserPersist;1");

                nsITransfer nst = Xpcom.CreateInstance("@mozilla.org/transfer;1");
                nst.Init(source, dest, t, e.Mime, 0, null, persist, false);

                if (nst != null)
                {
                    persist.SetPersistFlagsAttribute(2 | 32 | 16384);
                    persist.SetProgressListenerAttribute((nsIWebProgressListener)nst);
                    persist.SaveURI(source, null, null, (uint)Gecko.nsIHttpChannelConsts.REFERRER_POLICY_NO_REFERRER, null, null, (nsISupports)dest, null);
                }

                myStream.Close();
            }
        }
    }
