Unable to save firebase redirect email in local storage from heroku but works fine in localhost

  firebase, javascript, mern, node.js, reactjs

So basically i am trying to save the email address that is being registered in firebase in local storage on redirect and my app is in Heroku but the local storage of my browser is unable to save it.However when using localhost no such issue occurs. Below is the link of my app. Please signup using your test email address and the registration screen should prepopulate the email address but it’s not working. I am able to successfully prepopulate it in localhost. In ‘Complete registration’ page enter email address field should prepopulate the email used to register in firebase. PLEASE HELP
