[keycloak-user] Browser not maintaining session for keycloak users

I am using openid-connect for authenticating users. After successful authentication, browser windows says: "Login Successful You may close this browser window and go back to your console application." However, even without closing the window if I relaunch my application (using keycloak.loginDesktop();) even within 10 seconds, still the login page appears instead of : you are already logged in. Browser: Firefox.
