Minor update needed in my code

I have made an extension which likes posts of fb one by one and after 5 seconds, page refreshes and then likes new post again one by one. The post which is already liked remains as it is. I am facing an issue that after 1 hour my I'd gets logged out. Mujhe bas yeh chaiye ki vo Waps se login ho jaye

I can pay max : 600 rupees
