Content Security Policy in Firefox Extension blocking local DataTables js

After downloading the js for DataTables, I attempted to load it onto my Firefox extension but encountered a Content Security Policy block:

Content Security Policy: The page’s settings blocked the loading of a resource at self (“default-src moz-extension://27d54fdf-40f3-4919-9314-f0f8b4715ef6”). Source: onfocusin attribute on DIV element. options.html

Content Security Policy: The page’s settings blocked the loading of a resource at self (“default-src moz-extension://27d54fdf-40f3-4919-9314-f0f8b4715ef6”). Source: $( document ).ready(functi....

I have added the Content Security Policy in my manifest.json file:

"content_security_policy": "default-src 'self'"

The scripts included in the head section are:

<script src="jquery-1.12.4.js"></script>
<script src="jquery.dataTables.min.js"></script>
<link rel="stylesheet" type="text/css" href="jquery.dataTables.min.css">

And this is my script on the options page:

<script type="text/javascript">
    $( document ).ready(function() {
        console.log( "ready!" );
        $('#example').DataTable();
    });
</script>

If anyone has any insights or solutions to offer, please let me know!

Answer №1

I encountered a comparable problem that I could not replicate using a different application. Interestingly, this issue only arises in Firefox and not Chrome. Once I transitioned to JQuery 2 or 3, the error disappeared entirely.
