Basically, the poster said "It seems to me that Facebook only wants you to access Facebook via the Newsfeed on its application and it's not difficult to see why, given that it makes its money with promoted pages and advertising."
I wanted to thank the user who suggested that I uninstall Facebook and reinstall a previous version available at apkmirror. I have my widget back and I have unchecked automatic updates so that Facebook can not delete my Widget again.Thankyou
