There's probably a different kind of intent for PDFs, so if we want to support this we have to register Firefox as an handler for that too.

We should re-test this after bug 1815739 is fixed.

I've retested on Focus Nightly 122.0a1 build from 12/6.
On Samsung Galaxy Note 8 (Android 9) the issue is fixed - setting Focus Nightly as default, opens the PDF files in custom tabs.

However, on Lenovo tablet M10 (Android 10), the issue is still reproducible.
