I have had my tablet for over a year and have had crashes since the beginning. I, the last day they have become worse . I have had at least 20 crashes today, even with only 1 tab open and searching something on Amazon (no video, no music taking memory). On top of it in the last hour the crashes are accompanied by flashing screen -only on Firefox. Please help. 8 am a great fan of Firefox. Here been using it for years on PCs, phones and tablets ... the only problem is frank is with this model of tablet. Thank you
