How to remove scrollbar in firefox 93?

Question

Mozilla Firefox

None of the methods helped:

html {
    -ms-overflow-style : none !important; 
    scrollbar-width    : none !important;
    overflow: -moz-scrollbars-none !important;
}

Everywhere everything is fine, except for firefox. From the last links I saw this one, which says that it seems like support for these prefixes and methods in general in firefox just fell off. And what about then?
