Today Firefox worked fine in the morning. When I came back to it in the afternoon, it would't stop crashing. I finally deleted it and had to sideload Firefox Focus. Overall it seems to work better but I apparently can't have tabs. Also, when I leave a website and go back, it's as if I've never been there and I have to start from scratch. How do I fix this? The almost worthless phone I'm using is a ZTE Fanfare 2 with a measly 8 gb. The SD card is 32 gb but seemingly useless for anything besides photos and videos. No, I can't afford another one and have no computer access.
