Continuous redirects for firefox

I have a SPA application in angular, which makes use of Auth0 for authentication.When I try to login on Firefox browser, the login is not successful. It keeps on redirecting continuously. However the login is successful for all the browsers: Chrome, Edge,IE etc. I have researched enough and the problem is still unresolved.
For more details about the problem get the entire details on the following link:

I have set up a SPA with auth0 in angular. While using Firefox browser, after go…ing to the authentication page, after entering credentials, it cannot redirect to the specified page. However, while using Chrome and Edge it works fine. Is there any known issue with FireFox Browser? I get the following error in console: > Object { error: "invalid_token", errorDescription: "Request has been terminated\nPossible causes: the network is offline, Origin is not allowed by Access-Control-Allow-Origin, the page is being unloaded, etc." } ### Description ``` public handleAuthentication(): void { this.auth0.parseHash((err, authResult) => { if (authResult && authResult.accessToken && authResult.idToken) { window.location.hash = ''; this.localLogin(authResult); this.router.navigate(['/home']); } else if (err) { // this.router.navigate(['/home']); console.log(err); } }); } ``` For Firefox, authResult is null while for other browsers, auth0 returns a valid token. I checked on auth0 community page and see the similar problem > https://community.auth0.com/t/continuous-redirect-to-authentication-in-firefox/7426 However I did not get any solution for this.

Hi @nitesh.kumar,

Welcome to the Auth0 Community!

This issue can be related to the parseHash function being called more than once. Can you console.log and check to make sure it is not being called more than once?

Thanks,
Dan
