If an error dialog, "Windows cannot find [URL]" pops up (or if two Firefox windows or tabs are opened) whenever you click on an Internet Shortcut or local HTML file in Windows, then you are experiencing a problem similar to that described in Bug 246078, in which URLs from other applications result in two Firefox windows or a window and an error dialog.

There are several workarounds in the bug report and discussion. Some are listed below.

The File Types Workaround

  1. Open Windows Explorer (Win+E).
  2. Go to Tools -> Folder Options -> File Types
  3. Select "Extension: (NONE)" and "File Type: HyperText Transfer Protocol".
  4. Go to Advanced -> Edit File Type -> Select "open" -> Edit
  5. Disable the DDE message box (which should contain "%1" or something similar).
  6. Repeat for "File Type: HyperText Transfer Protocol with Privacy" and any other protocols you want to fix.
  7. Repeat for "Extension: HTML" and "File Type: Firefox Document".

The Registry Workaround

Be sure you are familiar with the Registry as this has a chance of corrupting your entire computer system if you bother other registry entries. [Source]

  1. In Start -> Run, type "regedit" and press Enter.
  2. Use the directory tree hierarchy to navigate to "HKEY_CLASSES_ROOT\HTTP\shell\open\ddeexec".
  3. Delete the "ddexec" folder.
