I have styled scrollbar of element on chrome using
aside::-webkit-scrollbar {
    width: 5px;
    color: skyblue;
}
aside::-moz-scrollbar {
    width: 5px;
    color: skyblue;
}
aside::-webkit-scrollbar-track {
    -webkit-box-shadow: inset 0 0 6px rgba(0,0,0,0.3); 
    border-radius: 10px;
}
aside::-moz-scrollbar-track {
    -webkit-box-shadow: inset 0 0 6px rgba(0,0,0,0.3); 
    border-radius: 10px;
}
aside::-webkit-scrollbar-thumb {
    border-radius: 10px;
    -webkit-box-shadow: inset 0 0 6px rgba(0,0,0,0.5); 
}
aside::-moz-scrollbar-thumb {
    border-radius: 10px;
    -webkit-box-shadow: inset 0 0 6px rgba(0,0,0,0.5); 
}
aside::-webkit-scrollbar-thumb{
    background: skyblue;
}
aside::-moz-scrollbar-thumb{
    background: skyblue;
}
as I tried to implement same thing on Firefox I found out Mozilla no more supports old styling scrollbar method...
Is there any way to style a scrollbar in Firefox now?
