Facebook profile pic is blurry in Ionic App

I’m using facebook authentication. Once the user is logged in I’m using the facebook profile pic as a temporary profile pic in the app.

ionViewDidLoad() {
this.user = firebase.auth().currentUser; // code from firebase docs

<ion-card *ngIf=“user”>
<img [src]=“user.photoURL”/>

The pic is blurry. Does anyone know of a way to improve the quality?
