I created a Firefox extension, was working fine until I updated to new version 15.0.1, and on very first line it is giving SyntaxError: illegal character : ��w

Posted

The code on first line is window.addEventListener("load", function(e) { onLoad(e); }, false); but if I open file from Error message link it shows this ��w�i�n�d�o�w�.�a�d�d�E�v�e�n�t�L�i�s�t�e�n�e�r�(�"�l�o�a�d�"�,� �f�u�n�c�t�i�o�n�(�e�)� �{� �o�n�L�o�a�d�(�e�)�;� �}�,� �f�a�l�s�e�)�;�

You may have saved files in an UTF-16 encoding instead of UTF-8, so check that.
You can open such extension files in Firefox via their chrome url.

Thank you, I already saved the js file using a java script editor, and that solved the problem.
