.deallinkactive {
display: inline;
float: right;
width: 508px;
padding: 5px;
font-size: 14px;
margin: 10px 10px 8px 8px;
border: 1.5px solid rgba(173, 38, 38, 0.541176);
-webkit-border-radius: 3px;
border-radius: 3px;
color: rgba(0, 0, 0, 1);
background: #ecf0f1;
-webkit-transition: all 0.5s ease;
-moz-transition: all 0.5s ease;
-o-transition: all 0.5s ease;
-ms-transition: all 0.5s ease;
transition: all 0.5s ease;
-webkit-animation: neon2 .2s ease-in-out infinite alternate;
-moz-animation: neon2 .2s ease-in-out infinite alternate;
animation: neon2 .2s ease-in-out infinite alternate;
  }

The Box shadow animation is perfectly working on Chrome and Mobiles but not on IE and Firefox. I have tried -webkit-box-shadow , box-shadow , moz-box-shadow and all the things I found on internet. If I replace text-shadow in box-shadow, text-shadow works. Help!!

Solution

First of all, your class .deallinkactive is pointing to a wrong keyframe, it says neon2, change that to neon. then remove -webkit- from all -webkit-box-shadow. Finally, @keyframes not supported in an inline or scoped stylesheet in Firefox bug 830056.

But you have an alternate:

@keyframes neon {
    0% {
        -webkit-box-shadow: 0px 0px 12px 0px rgba(255,17,120,1);
        -moz-box-shadow: 0px 0px 12px 0px rgba(255,17,120,1);
        box-shadow: 0px 0px 12px 0px rgba(255,17,120,1);
    }
    100% {
        -webkit-box-shadow: 0px 0px 12px 0px rgba(255,153,0,1);
        -moz-box-shadow: 0px 0px 12px 0px rgba(255,153,0,1);
        box-shadow: 0px 0px 12px 0px rgba(255,153,0,1);
    }
}

.deallinkactive {
    display: block;
    float: right;
    width: 508px;
    padding: 5px;
    font-size: 14px;
    margin: 10px 10px 8px 8px;
    border: 1.5px solid rgba(173, 38, 38, 0.541176);
    -webkit-border-radius: 3px;
    border-radius: 3px;
    color: rgba(0, 0, 0, 1);
    background: #ecf0f1;
    transition: all 0.5s ease;
    animation: neon .2s ease-in-out infinite alternate;
}

Fiddle example

It works on modern browsers (chrome, firefox, safari, IE10+). Hope it helps.
