Answer 1

for firefox you must set height:'100%' for body and html elements as follows:

html, body {
    height: 100%;
}

.container {
    height: 100%;
    min-height: -moz-available; /* WebKit-based browsers will ignore this. */
    min-height: -webkit-fill-available; /* Mozilla-based browsers will ignore this. */
    min-height: fill-available;
}

this worked for me. I hope this can help you.
