In Firefox PDF attachments won't download for me, they will navigate to the literal blob: URL and away from the ProtonMail client (both on mail. and old.). Blobs used for downloads should not have a specific mime type the same way server responses shouldn't if they need to trigger a download.
I haven't tested this, all I did was some ctrl+f on the source and I assume this is the right fix. It's what I was assuming to be the root cause in the first place. Do with it whatever you want.
This is in response to my support ticket 1005204
