I don't know how I did removed the firefox app icon from the main scren
How can I restore it?
My phone is using Android 5.1 and it is a TPLink Neffos C5
Edit: The icon is not present in the app drawer
But at the applications section
As unusual, my phone does not support app drawer, but it comes with a feature named Hidden apps, the solution was:
Now it should appear at the end of your screens.
