When trying to set Firefox to open a file on Windows 11, it is overwritten by Firefox Nightly. I have both branches installed.

This is how it goes when attempting to set Firefox as a default application in my machine:

  1. "Apps > Default Apps"
  2. .mp4 (for example)
  3. click the button below that displays the current default application
  4. Firefox Nightly appears in this menu
  5. "Choose an app on your PC"
  6. "C:\Program Files\Mozilla Firefox" ... "firefox.exe" ... "Open"
  7. Firefox Nightly remains in this menu

I cannot get Firefox to appear as an available app in this menu. The only workaround, although inconvenient, is to drag and drop files straight into Firefox.

Any help would be much appreciated. Thanks.

The problem is due to Firefox and Firefox Nightly using the same name for the executable: "firefox.exe". Fixed by renaming either executable.
