I've been trying to get progressive web apps to work on my phone. Have got to say Chrome is way ahead of Firefox in this department.
The Firefox PWA implementation is just full of bugs. For example, I'm trying to use the Google Maps PWA but it won't load unless I also open the full Google Maps website in Firefox at the same time. I was also trying to use the Uber PWA but it can't access location services even if I grant it the permission.
All of this works fine in the Chrome implementation.
