Just built it from source while waiting for Google to approve the app, and it's great. I had to use Firefox for the PWA because I need links to open in firefox when I click on them, but Firefox doesn't handle PWAs vey well. The native app fixes all these problems. Excited for it to be on the Google Play Store!
Also aeharding@lemmy.world will you upload the android app to F-droid? It would be nice to have it there rather than having to install it from the play store.
As a ex-web developer: it is not Firefox that is broken, but those sites. They optimize for Chome and don't check firefox. I don't blame them, considering percentage of users, but it is not FF fault.
Google's apps are especially slower than in chrome
