Am getting this message when I attempt to open Firefox: "The application or DLL F:\Program Files\ Mozilla Firefox\nss3.dll is not a valid Windows image. Please check this against your installation diskette."

I had responded favorably to the upgrade message from Firefox but after the download I kept getting a Firefox message that I had to close all other instances of Firefox running before the installation process could complete. There were no other open Firefox programs! I re-booted and tried to open Firefox, and the Windows alert already cited started, and Firefox will not open. Checking via Windows Explorer it appears that I still have version 3.6.

I resolved the problem. I went to CNet and re-downloaded the upgrade. It proceeded as intended and the upgrade is installed and running with no loss of plug-ins, bookmarks, etc.
