chrome extension (javascript) foR facebook

Hi, I am a software developer and also a tester, I can complete this task complete and correctly. But I want to propose a both that can execute this task from an excel file or even other open source solution; if you want a chrome extention I can performe but for security and portability a both could be better. ¿How it will work? Simple, it will execute the below steps. 1. Open a question box to know whther you want to delete the facebook activity log. 2. Once you click on "Yes" it will ask for username and password. (The data will not saved) 3. A browser will be displayed. 4. The both will get login. 5. The both will open the log site. 6. The both will delete ol activity log. 7. The both will get logout. The task will be completed. It will be performed in one or two days. Regards, Juan Hernandez
