firebase deploy is not working properly

My site is working properly on my computer. But when i use the commands:

firebase init

and then

firebase deploy

the site stops working.

My website has a login/signup screen. after successful signup/login, it shows the dashboard. The entire code is in the same file. Now, when I deploy, my login screen is shown perfectly, and when i signup, the entry is also shown on my firebase console. But it does not open the dashboard and stays on the same page. Can you help me please?
