    -webkit-transform: scale(1.0);
    opacity: 0.75;
  }
  50% {
    -webkit-transform: scale(1.2);

  }
}

div.pulse { opacity: 0.75; }
div.pulse:hover {
  -moz-animation-name: pulse; 
  -moz-animation-duration: 0.5s; 
  -moz-animation-iteration-count: 1;

  -webkit-animation-duration: 0.5s; 
  -webkit-animation-iteration-count: 1;

Anyone can tell what i do wrong? Whay dont work in mozila?

Answer 1

You need to define the FF version of the animation and transform as well as the webkit version

@-moz-keyframes pulse { /* older versions of FF */
  from {
    -moz-transform: scale(1.0);
    opacity: 0.75;
  }
  50% {
    -moz-transform: scale(1.2);
    opacity: 1.0;
  }
  to { 
    -moz-transform: scale(1.0);
    opacity: 0.75;
  }
}

@keyframes pulse {
  from {
    transform: scale(1.0);
    opacity: 0.75;
  }
  50% {
    transform: scale(1.2);
    opacity: 1.0;
  }
  to { 
    transform: scale(1.0);
    opacity: 0.75;
  }
}
