Firefox clears tab in background

I use Firefox instead of apps for '''everything'''. And do often have 5-10 tabs open. Phone: poco x7 pro 8GB Android: 16 This problem is not present in my older phone.(Android 13) It clears the tabs, whenever Firefox is sent to the background. That means all the tabs have to be reloaded. That means battery consumption, data consumption, delay, losing my place in videos ( I watch YouTube on Firefox too) . I am willing to do anything short of rooting the phone.
