Every now and then the screen if my phone gets blank and regains it's gorm may be it seems some overlapping issues through system interventions as I could see a shared browser is present in my phone of wch I am not aware off. So I would request Mozilla to activate only the Mobile data as I am not connected with any wi-fi connection to my internet services so see to that no number is linked or overlapped especially the organisational ones Regards & Gratitude K S KRISHNANANDA PRABHU
