This title is a bit misleading. Progressive Web Apps are supported on Firefox mobile, on android at least. The real issue people should be discussing is Apple not supporting PWAs, or in fact, any browser engine other than Safari on iPhones. It's the real blocker to wider adoption of PWAs (and many other features!) Until that happens, whether Firefox desktop / other platforms support this specific behaviour (Single-Site Browser) is a bit moot as it's an edge case compared to 50% of mobile users.

PWA is a bag of features that is mostly supported on iOS. You can have fullscreen apps that run offline, launched from the home screen. However, you can not trigger an installation prompt like on Android.

  You also have a ton of limitations like no background updates, no location, no bluetooth, the app’s data gets deleted after 7 days, if you don’t use it, etc

    > the app’s data gets deleted after 7 day This is not true, it's a misconception about how the seven-day-counter works when the app is installed on the home screen. Nevertheless, persistent data is a concern, because the standards do not specify how long data must be kept, so it could get wiped at some point, for example when the device is low on disk storage.

      This. Majority of both Apple’s and Mozilla’s stance are based on the lack of standards for the PWA. The final checkboxes for both browsers have unchecked usually reflect the lack of clear specs from Google (since they shipped publicly before draft in W3C) pushed to help their own agenda.

      Honestly as a user having no say in when your data gets deleted really sucks. Why anyone considers iOS any more than a terrible joke is beyond me.

    Bluetooth is widely used for user tracking. There are good reasons why a lot of arbitrarily introduced features haven’t been adopted by Apple or Mozilla.
