  • Hi,

    Thank you for the submission.  This will happen when the MIME type or “Content-Type” is not understood by the browser.

    I looked at the network details in Edge’s debugger and found an entry that had the “Content-Type” set to ‘js’ which is not understood by Edge as it is not a proper content type for javascript.  Because of this when Edge is given a response with content it does not understand it will download it.  I have attached two screenshots showing an understood Content-Type and one that is improper from the site you gave me.

    Here is a post on the topic from stackoverflow:

    In summary, the site owner needs to update their site to correct this issue.

    Hope this helps,
