TBA - Audit Progressive Web App (PWA) Implementation
[| Progressive Web Apps] allow "installing" a webapp (some minimal version of a website) as an app on a phone/tablet (Android, iOS, ...). Basically, they're platform independent apps, using HTML/CSS/JS. This sounds useful, but if a user installs a PWA using TBA and then clicks the icon on their homescreen, does it open in TBA or in Firefox or does it let the user choose? This blog  shows there is a difference between the PWA homescreen-icon created by Chrome and created by Firefox, so the homescreen-icon probably links to the app that originally installed it, but we should make sure these nifty little programs don't introduce a complete proxy bypass because the user installs the app with TBA and then opens it with Fennec.
