title: Firefox warns that "text/html is not a valid JavaScript MIME type" for a 404 script
body: <p>I chrome I get <code>404 not found</code> for the cached file but in mozila it is :</p>
  
  <blockquote>
    <p>The script from “<a href="https://sqa.micro-logic.ca/wp-content/cache/autoptimize/js/autoptimize_c25390e0b7b5140a1757c102b959bd63.js" rel="nofollow noreferrer">https://sqa.micro-logic.ca/wp-content/cache/autoptimize/js/autoptimize_c25390e0b7b5140a1757c102b959bd63.js</a>” was loaded even though its MIME type (“text/html”) is not a valid JavaScript MIME type.</p>
  </blockquote>
  
  <p>In both browser this error prevents my others scripts to be loaded and breaks my whole page. What is the second one ( mozila ) means? I didn't found a way to fix it. Thank you!</p>
