The Firefox app crashes constantly. It either freezes and forces me to restart Firefox, or it will freeze for a few seconds and then send me straight to the Home Screen without a transition or error message. I can pretty consistently make Firefox freeze and/or crash by bringing up an iPhone system window - for example, if the "low battery" notification comes up, or if I swipe down the Notification Center from the top, or if I switch to a different app and then back to Firefox, or if the screen goes to sleep and I unlock it. Sometimes this starts a crash loop where I try to launch Firefox, the logo comes up on my screen, and then it crashes back to the Home Screen. Again, no error message. Also, when I tap the menu button it either doesn't respond or takes upwards of 3-4 minutes to bring up the options. I use an iPhone 8, version 15.6, but this has been going on for at least two previous system updates. I have updated Firefox (twice now) and cleared all history, cache, and cookies, to no change. I've tried Firefox Focus and it doesn't have any of these problems, but the lack of tabs is a problem. Are there any error logs stored somewhere I can check?
