CSS悬停效果在Firefox

Question

我有一个悬停效果纯CSS，它适用于Chrome和Opera，但在Firefox中不起作用。它是白色的，当你悬停时，你会看到后效果图像。

以下是包含HTML和CSS代码的代码段。

.hovereffect {
  width: 100%;
  height: 100%;
  float: left;
  overflow: hidden;
  position: relative;
  text-align: center;
  cursor: default;
}

.hovereffect .overlay {
  position: absolute;
  overflow: hidden;
  width: 80%;
  height: 80%;
  left: 10%;
  top: 10%;
  border-bottom: 1px solid #FFF;
  border-top: 1px solid #FFF;
  -webkit-transition: opacity 0.35s, -webkit-transform 0.35s;
    -moz-transition: opacity 0.35s, -webkit-transform 0.35s;
  transition: opacity 0.35s, transform 0.35s;
  -webkit-transform: scale(0,1);
    -moz-transition: opacity 0.35s, -webkit-transform 0.35s;
  -ms-transform: scale(0,1);
  transform: scale(0,1);
}

.hovereffect:hover .overlay {
  opacity: 1;
  filter: alpha(opacity=100);
  -webkit-transform: scale(1);
    -moz-transform: scale(1);
  -ms-transform: scale(1);
  transform: scale(1);
}

.hovereffect img {
  display: block;
  position: relative;
  -webkit-transition: all 0.35s;
    -moz-transition: all 0.35s;
  transition: all 0.35s;
}

.hovereffect:hover img {
  filter: url('data:image/svg+xml;charset=utf-8,<svg xmlns="http://www.w3.org/2000/svg"><filter id="filter"><feComponentTransfer color-interpolation-filters="sRGB"><feFuncR type="linear" slope="0.6" /><feFuncG type="linear" slope="0.6" /><feFuncB type="linear" slope="0.6" /></feComponentTransfer></filter></svg>#filter');
  filter: brightness(0.6);
  -webkit-filter: brightness(0.6);
    -moz-filter: brightness(0.6);
}

.hovereffect h2 {
  text-transform: uppercase;
  text-align: center;
  position: relative;
  font-size: 17px;
  background-color: transparent;
  color: #FFF;
  padding: 1em 0;
  opacity: 0;
  filter: alpha(opacity=0);
  -webkit-transition: opacity 0.35s, -webkit-transform 0.35s;
    -moz-transition: opacity 0.35s, -webkit-transform 0.35s;
  transition: opacity 0.35s, transform 0.35s;
  -webkit-transform: translate3d(0,-100%,0);
     -moz-transform: translate3d(0,-100%,0);
  transform: translate3d(0,-100%,0);
}

.hovereffect a, hovereffect p {
  color: #FFF;
  padding: 1em 0;
  opacity: 0;
  filter: alpha(opacity=0);
  -webkit-transition: opacity 0.35s, -webkit-transform 0.35s;
     -moz-transition: opacity 0.35s, -webkit-transform 0.35s;
  transition: opacity 0.35s, transform 0.35s;
  -webkit-transform: translate3d(0,100%,0);
    -moz-transform: translate3d(0,100%,0);
  transform: translate3d(0,100%,0);
}

.hovereffect:hover a, .hovereffect:hover p, .hovereffect:hover h2 {
  opacity: 1;
  filter: alpha(opacity=100);
  -webkit-transform: translate3d(0,0,0);
    -moz-transform: translate3d(0,0,0);
  transform: translate3d(0,0,0);
}

 <div class="hovereffect">
