Only on Firefox “Loading failed for the script with source”

I just had the same issue on an application that is loading a script with a relative path.

It appeared the script was simply blocked by Adblock Plus.

Try to disable your ad/script blocker (Adblock, uBlock Origin, Privacy Badger…) or relocate the script such that it does not match your ad blocker’s rules.

If you don’t have such a plugin installed, try to reproduce the issue while running Firefox in safe mode.

  • If you cannot reproduce it in safe mode, it means your issue is linked to one of your plugins or settings.
  • Otherwise, it might be a different issue. Make sure you have the same error message as in the question. Also look at the network tab of the developer tools to check if your script is listed (reload the page first if needed).
