Try opening the file outside Firefox. To do this: 1. Save the target file on your local drive (Right-click "Save link as"). 2. Using Windows Explorer, open the folder where you saved the file. 3. Double click the file to open it (it should default to Excel). If this fails, right-click and navigate the context sensitive menu to "Open With" and select Excel.

That usually happens if the server sends the file as text/plain
Firefox will display such a file as text file instead of showing the "Open with" download dialog.
You will have to safe that file and open it in Excel like posted above.
