Compatibility of zoom on Firefox

my requirement is to zoom the entire web page through css. At first, using zoom, found that it is not supported on Firefox. Baidu later found a compatible processing method on Firefox:

body {
  zoom: .8;
  -moz-transform: scale(.8, .8);
  -moz-transform-origin: top center;
}

it is true that the zooming effect can be achieved on Firefox, but it may be because the website I made is a full-screen website, which leads to a blank after zooming twice.
is there a better way to handle it on Firefox? thank you

.

suddenly found that the picture can not be uploaded. Google has a perfect effect because it supports zoom, but Firefox uses scale to set the width of 100% of the width of the page. After zooming, it is no longer 100% of the wide mouth, but 80%. What should I do?
