Невозможно настроить на любых вариантах мозиллы

Worked exactly as I need.

Lgg4 and lgg5 android 6.0.1
A little glitchy to set up but basically go to menu add-ons home button, then enter your home page. Close/ QUIT. Fire Fox then restart.
After ff last upgrade i had to unistall and reinstall but worked just fone after doing those set up steps. Ypur icon replaced the new privacy icon added to this new version design of FF but its in the menu as before so no problem
One thing, FF blocked my initial attempt to install app after update but offered me choice to allow despite their block. Why suddenly is your app blocked and www.google.ca an insecure connection? Maybe issue is FF update and not your app.
