Download on Firefox 97.0 creates a file that says "Invalid Request" #417

When pressing Ctrl+S on a processed image on Firefox 97.0 (on Gentoo Linux), the result is an image that says "Invalid Request", as if the produced file wasn't grabbed but instead a new request has been started.

It used to work in the past, with older Firefox versions, so it could be related to changes in Firefox.

For a long time, I believe this behavior in Firefox is a bug.

  1. Firefox will try to re-fetch the image data with a GET Request before saving it.
  2. However, the output image of waifu2x is an image data generated by a POST Request with Parameters, so it is impossible to fetch it with a GET Request.

I think this behavior is completely wrong and cannot be fixed by the user.

Also, the download button should work.

...Huh. You know, I just utterly missed that button. You're right, the button does work.

Excuse me, I appreciate the work you do on the waifu2x project, but just wanted to ask what is the point of the Download button instead of simply having the Convert button, as the Download button doesn't do anything and Convert can simply be used to download the image right afterwards. Thank you.

Clicking the Download button will automatically download the result image. The image is automatically downloaded to the web browser's Download Folder without the Save As dialog box appearing.

In some browsers(Firefox or Mobile's browser), Save As feature does not work. That's why there is the download button.
