/node_modules/rxjs/dist/cjs/internal/util/reportUnhandledError.js:13
            throw err;
            ^

Expected behavior

AngularFire should check if rendering on a browser before calling Performance code (which relies on window being available)

Actual behavior

No check is done, so when calling the Performance library, this above error occurs as soon as pre-rendering on the server happens and window is accessed but isn't available due to not running in a browser

For others hitting this issue you can work around it like so:

constructor(
    private performance: Performance,
    @Inject(PLATFORM_ID) private platformId: Object
  ) {
    this.isBrowser = isPlatformBrowser(this.platformId);
    if (this.isBrowser) {
      this.startupTrace = trace(this.performance, 'angularStartup');
      this.startupTrace.start();
    }
}
