On macOS the previous behaviour in Firefox was that the text content from the drag&drop was sent to the application I dropped to (and still works this way when doing so to the open application). But now Firefox downloads the image preview that I use to enable the drag&drop with into a temp folder, giving it a serial name. Is there any setting to revert back to the old behaviour? And if, not can you implement one please?
