Hi,
Using a fresh PWA starter kit, I install Firebase following this tutorial.

It used to work with previous projects (2 weeks ago), but now 'import Firebase from ‘firebase’ returns an error : export ‘default’ (imported as ‘Firebase’) was not found in 'firebase’.

I tried the same code inside a fresh vue-webpack-boilerplate and no bugs, it works. So I’m thinking maybe a conflict with another component inside the Quasar starter kit?
