1900820 - [Meta] Make share work when reading PDF

Status: ASSIGNED

Description

Not sure if this is Android only, but:

I use Firefox Nightly on Android set as default PDF reader and if I download a PDF say from a whatsapp chat, it is shown with a content://com.whatsapp... url in Firefox. If I then open the three dots menu and select the share icon and then an email client, it will share that link (which is useless elsewhere), not a copy as attachment. This breaks my former habits from the times I had Acrobat as default reader: Receive (in whatsapp), read (Acrobat), share (to email/whatever) - now I have to go back to whatsapp for sharing.

This is probably a deal breaker for the signature feature. I can imagine lots of people will want to sign PDFs and then share them.

We'll need to temporarily copy the PDF into the cache storage, and remove it after it's succesfully shared.

It might be worth having a WorkManager cleaning the cache periodically to make sure we don't leave any file behind.
