1790659 - add telemetry for detecting partially virtualized profiles

Status: NEW

(Firefox :: Installer, enhancement, P2)

Description

[[e-mail] (:bhearsum)]

We have at least some number of MSIX users whose profiles are in a partially virtualized state -- that is, part of their profile is in a virtualized directory (eg: %LocalAppData%\Packages\Mozilla.Firefox.Beta_gmpnhwe7bv608\LocalCache\Roaming\Mozilla) and the other part in an unvirtualized directory (%appdata%\Mozilla). We're planning to unvirtualize our MSIX package, and the volume of the problem may affect how we deal with these profiles when we do.

nrishel - can you add the specifics on how you think we can detect this state?

Discussed offline - I'll be taking over this task. I'll outline the specifics of state detection in the revision itself.
