I am a student using Android I installed Firefox believing in privacy and features. Now I feel like cheated because it doesn't provide the necessary options of print to PDF and option-full share menu. I wonder why on earth such a famous browser doesn't provide these basic very basic necessary options ! I really don't want to leave Firefox because I love it in a way ! Yet I am being forced to move to another better browser because it's my routine requires it. I am waiting for the next update without hope.
