The full code is following...>>>>

package com.example.prateek.holachat;

import android.content.Intent;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;    
import android.view.Menu;    
import android.widget.Toolbar;    
import com.google.firebase.auth.FirebaseAuth;   
import com.google.firebase.auth.FirebaseUser;

public class MainActivity extends AppCompatActivity {

    private FirebaseAuth mAuth;
    private Toolbar mtoolBar;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        mAuth = FirebaseAuth.getInstance();

        mtoolBar = (Toolbar) findViewById(R.id.toolBarNew);
        setSupportActionBar(mtoolBar);
        getSupportActionBar().setTitle("HOLA !");


    }


    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        super.onCreateOptionsMenu(menu);

        getMenuInflater().inflate(R.menu.main_menu,menu);

        return true;
    }


    @Override
    public void onStart() {
        super.onStart();
        // Check if user is signed in (non-null) and update UI accordingly.
        FirebaseUser currentUser = mAuth.getCurrentUser();

        if (currentUser == null) {

            Intent startIntent = new Intent(MainActivity.this,StartActivity.class);
            startActivity(startIntent);
            finish();

        }


    }

All the v7 libraries are used to support devices with old android versions. If you want to provide a the support use import android.support.v7.widget.Toolbar with setSupportActionBar()

Otherwise as in your case you have import android.widget.Toolbar; so use setActionBar() instead.
