App startup failure with VueFire plugin

I’ve started this Vue (version 2.6.10) web app to follow along this Quill tutorial that uses the vuefire plugin for Firebase realtime document syncing suppport. As soon as I add the import and register the plugin,I get the following error emanating from the main.ts file. Uncaught TypeError: Cannot read property 'install' of undefined at Function.Vue.use (vue.runtime.esm.js?2b0e:5100) at eval (main.ts?bc82:9) at Module../src/main.ts (app.js:3317) at __webpack_require__ (app.js:767) at fn (app.js:130) at Object.1 (app.js:3403) at __webpack_require__ (app.js:767) at app.js:902 at app.js:905

My repo is a bare bones project and can be cloned from: https://github.com/calirails/wysiwyg-quill

I searched web and scanned existing issues and came across this [reported issue] (https://github.com/vuejs/vuefire/issues/273) that was open-ended, and claimed to have been resolved by moving the import statement for vuefire right after the import of Vue itself; however, that didn’t resolve my error.

There is no bug, please read the docs: https://vuefire.vuejs.org/vuefire/getting-started.html#plugin, there is no default export in Vuefire anymore

import { firestorePlugin } from 'vuefire'

Thanks @posva! Confirmed that I can successfully import both the RTDB (Firebase) as well as the firestorePlugin (Firestore) using that VueFire guide.
