How to force Firefox to download a pdf file instead of opening it?

let blob = new Blob([data], { type: 'application/pdf' })
        let link = document.createElement('a')
        link.href = URL.createObjectURL(blob)
        link.setAttribute('target', '_blank')
        link.download = file_name
        link.click()
