Yeah, it makes sense. I have a habit of always closing it when I put my phone back in my pocket or wherever – it makes a huge difference in saving battery. I keep about 4-5 tabs that are dedicated for things I use regularly enough, and then any tabs I open beyond that get closed also.
Though just this week actually I get a weird message when I open Firefox again. Let me look …
“Failed to read the configuration file. Please contact your system administrator.” … when I hit OK Firefox closes, then reopens. But all my tabs are there and I don’t notice anything wrong.
It persists after a phone restart too. Haven’t had time to poke around for a reason/resolution. My life is a mess haha.
