I have Javascript code that attempts to paste an image file, which has been copied from the Windows clipboard. This code works perfectly well in Chrome and Edge but not in Firefox. It will only work in Firefox, if the image is copied from an image-editing program, e.g. Paint.
A fragment of the event handler is similar to this:
var items = (e.clipboardData || e.originalEvent.clipboardData).items;
When executed using Firefox, the files collection in e.clipboardData is empty, as is the items collection.
I am aware that this is a duplicate question, that was asked 3 years ago: Javascript clipboardData.items and clipboardData.files are empty when pasting an image
I'm asking it again in the hope that someone knows of a work-around to this issue, or at least, an admission from Firefox that they do not support this functionality.
