I want do develop an app for Firefox OS that should handle tickets inside *.pkpass files.
The problem is, there seems to be no way to get a pkpass file from an email if it's attached as an attachment nor does the browser allows me to download it directly so the only way would be is to download it from the app directly which is, for my application, pretty much negating the purpose of an app (tickets are delivered using email and are not publicly available online, so the end user would need to download a ticket from an email and open it using the application which will verify-unpack it and store the data in a separate data storage).
Is there any way to download it to a device without using an app? Or it's not currently possible at all?
