This problem has been on my phone for years, through many iOS versions and several iPhones. I'm guessing its something in my settings but I have no idea what. Basically, when I use Firefox on my iPhone and switch away to another program, when I switch back to FIrefox, it loses its connection to the site I was using and goes to its home page. Yes, really! If things were normal, I should be able to switch away and switch back any time at all, but it pretty much always "crashes" when I do that. But I don't want to call it a crash, because Firefox stays open and happy, but just navigates away from the URL I'd been on. What might I check in order to pursue a "fix" (I doubt that something is broken!). Thanks.

Quick followup - When I'm using FIrefox and simply put my phone to sleep (push the button on the right side, sorry, I forget the name), when I wake the phone Firefox does that same thing and leaves the page I was on and opens the home page.
