我正在尝试使用CSS和SVG创建简单的动画：旋转齿轮。该动画可以在Chrome浏览器中完美运行，但不能在Firefox中运行。这是运行中的代码：

齿轮是SVG文件中的路径：

<div class="svg">
    <svg x="0px" y="0px" width="200" height="200" viewBox="0 0 200 200" xmlns="http://www.w3.org/2000/svg">
    <title>PDP</title>
    <text x="44" y="120" class="gear_text">PDP</text>
    <g transform="translate(50%, 50%)">
        <path id="gear1" class="gear go-clockwise" x="0px" y="0px" d="m91.63252,0l-4.16735,23.73752l0.01604,0.01606c-5.09374,0.83228 -10.02215,2.16622 -14.72963,3.9428l0,-0.01584l-15.46727,-18.48038l-14.53742,8.39871l8.25439,22.63163l0.03211,0.01585c-3.9412,3.23531 -7.55353,6.86028 -10.78684,10.8031l-0.01604,-0.04816l-22.63164,-8.25463l-8.39871,14.53743l18.48035,15.48333c-1.77354,4.70347 -3.09585,9.62447 -3.92695,14.71362l-0.01604,-0.01586l-23.73753,4.16734l0,16.79736l23.73753,4.16735l0.01604,-0.01587c0.83109,5.08915 2.15341,10.01014 3.92695,14.71381l-18.48035,15.48312l8.39871,14.53743l22.63164,-8.25444l0.01604,-0.04832c3.23331,3.94261 6.84564,7.56799 10.78684,10.80287l-0.03211,0.0159l-8.25439,22.63168l14.53742,8.39873l15.46727,-18.48027l0,-0.01582c4.70748,1.77637 9.63589,3.11047 14.72963,3.94278l-0.01604,0.01587l4.16735,23.73772l16.78132,0l4.16733,-23.73772l-0.01603,-0.01587c5.09294,-0.83009 10.02274,-2.15297 14.72985,-3.92696l15.4831,18.48047l14.53743,-8.39871l-8.27046,-22.63173c3.93234,-3.22687 7.54289,-6.83942 10.771,-10.7708l22.64757,8.25439l8.38263,-14.53741l-18.4642,-15.48308c1.77402,-4.70432 3.11153,-9.62388 3.94283,-14.71384l23.73775,-4.15126l0,-16.79738l-23.73775,-4.16735c-0.83148,-5.08432 -2.17067,-9.99828 -3.94283,-14.69775l18.4642,-15.4831l-8.38263,-14.53745l-22.64757,8.25443c-3.2281,-3.93136 -6.83842,-7.54391 -10.771,-10.77079l8.27046,-22.63168l-14.53743,-8.39871l-15.4831,18.48042c-4.70711,-1.77378 -9.63691,-3.09688 -14.72985,-3.92696l0.01603,-0.01586l-4.16733,-23.73761l-16.78132,0l0,-0.00011l0,0zm8.39869,40.8716c32.67677,0 59.17564,26.48283 59.17564,59.1596c0,32.67677 -26.49887,59.15962 -59.17564,59.15962c-32.67677,0 -59.15962,-26.48285 -59.15962,-59.15962c0,-32.67677 26.48286,-59.1596 59.15962,-59.1596z" stroke-dashoffset="0" stroke-miterlimit="4" stroke-linejoin="round" stroke-linecap="round" stroke-width="2"/>
    </g>
</svg>

然后使用CSS来应用动画：

.svg {
  width:200px;
  height:200px;
  float:left;
  position: fixed;
  top: 20px;
  left: 50px;
}

.go-clockwise {
  -webkit-animation: clockwise 3s infinite linear;
  -moz-animation: clockwise 3s infinite linear;
}

.go-counter-clockwise {
  -webkit-animation: counter-clockwise 3s infinite linear;
  -moz-animation: counter-clockwise 3s infinite linear;
}
path.gear{
  fill: #3f3f3f;
}
text.gear_text{
  font-size: 55px;
  font-weight: 900;
  fill: #3f3f3f;
}

@-webkit-keyframes clockwise {
  0% {
    -webkit-transform: rotate(0deg);
    -moz-transform: rotate(0deg);
    -ms-transform: rotate(0deg);
    -o-transform: rotate(0deg);
    transform: rotate(0deg);
    -webkit-transform-origin: center center;
    -moz-transform-origin: center center;
    transform-origin: center center;

  }

  100% {
    -webkit-transform: rotate(360deg);
    -moz-transform: rotate(360deg);
    -ms-transform: rotate(360deg);
    -o-transform: rotate(360deg);
    transform: rotate(360deg);
    -webkit-transform-origin: center center;
    -moz-transform-origin: center center;
    transform-origin: center center;

  }
}

@-moz-keyframes clockwise {
  0% {
    -webkit-transform: rotate(0deg);
    -moz-transform: rotate(0deg);
    -ms-transform: rotate(0deg);
    -o-transform: rotate(0deg);
    transform: rotate(0deg);
    -webkit-transform-origin: center center;
    -moz-transform-origin: center center;
    transform-origin: center center;

  }

  100% {
    -webkit-transform: rotate(360deg);
    -moz-transform: rotate(360deg);
    -ms-transform: rotate(360deg);
    -o-transform: rotate(360deg);
    transform: rotate(360deg);
    -webkit-transform-origin: center center;
    -moz-transform-origin: center center;
    transform-origin: center center;

  }
}

@-webkit-keyframes counter-clockwise {
  0% {
    -webkit-transform: rotate(0deg);
    -moz-transform: rotate(0deg);
    -ms-transform: rotate(0deg);
    -o-transform: rotate(0deg);
    transform: rotate(0deg);
    -webkit-transform-origin: center center;
    -moz-transform-origin: center center;
    transform-origin: center center;

  }

  100% {
    -webkit-transform: rotate(-360deg);
    -moz-transform: rotate(-360deg);
    -ms-transform: rotate(-360deg);
    -o-transform: rotate(-360deg);
    transform: rotate(-360deg);
    -webkit-transform-origin: center center;
    -moz-transform-origin: center center;
    transform-origin: center center;

  }
}

@-moz-keyframes counter-clockwise {
  0% {
    -webkit-transform: rotate(0deg);
    -moz-transform: rotate(0deg);
    -ms-transform: rotate(0deg);
    -o-transform: rotate(0deg);
    transform: rotate(0deg);
    -webkit-transform-origin: center center;
    -moz-transform-origin: center center;
    transform-origin: center center;

  }

  100% {
    -webkit-transform: rotate(-360deg);
    -moz-transform: rotate(-360deg);
    -ms-transform: rotate(-360deg);
    -o-transform: rotate(-360deg);
    transform: rotate(-360deg);
    -webkit-transform-origin: center center;
    -moz-transform-origin: center center;
    transform-origin: center center;
  }
}

使用CSS是首选方法，因为我正在动态应用该类。（向下滚动时为逆时针方向，向上滚动时为顺时针方向），但是出于这个问题的目的，我只应用一个类。Chrome可以很好地实现它，但是Firefox似乎
并未采用-moz-transform-origin
属性。不管我用什么，Firefox似乎都从（0,0）的原点开始应用转换，而Chrome接管了transform-origin属性并正常工作。

我已经尝试了几乎所有可以找到的东西。谁有想法？
