deploying on firebase with multiple url emberjs app

i recently just deployed an emberjs app with 3 routes on firebase, but it seems to give me a 404 page when going to the last 2 routes. I have my emberjs console open and it only picks up the first route.

i've also configure firebase.json file by adding a rewrite option and still no luck.

here is my app sample http://ift.tt/1I6EmSB

if you click on snippets and about, it just redirects me to a 404 page. also if you open ember console. it only shows 1 route.
