Fenix: [Bug] Download digital certificate pdf COVID19

[xpwd-lab]

Hello

I can't download the pdf of the digital certificate COVID19 on Firefox Preview. It works on Firefox Windows.

The PDF is generated on the fly. I think that GeckoView can't handle that properly right now, whereas Gecko can.

Does not seem to be the blob: issue. Attached are the headers that desktop sees.

On the contrary, I think it is the blob issue:

From https://media.interieur.gouv.fr/certificate.js

$('#form-profile').addEventListener('submit', async event => {
  event.preventDefault()

  saveProfile()
  const reasons = getAndSaveReasons()
  const pdfBlob = await generatePdf(getProfile(), reasons)
  downloadBlob(pdfBlob, 'attestation.pdf')

  snackbar.classList.remove('d-none')
  setTimeout(() => snackbar.classList.add('show'), 100)

  setTimeout(function () {
    snackbar.classList.remove('show')
    setTimeout(() => snackbar.classList.add('d-none'), 500)
  }, 6000)
})

function downloadBlob (blob, fileName) {
  const link = document.createElement('a')
  var url = URL.createObjectURL(blob)
  link.href = url
  link.download = fileName
  document.body.appendChild(link)
  link.click()
}

@kbrosnan is there a link to the blob issue?

Now we have support for blob URLs. QA please help us to verify if this website is working as expected.
