In the dashboard Theme Editor, chose the content-footer.php file.

Insert the following code between the footer tags, beneath any existing code:

<div style=”display: block !important; width: 100% !important; height: 80px !important; padding: 20px 0px !important; overflow: hidden !important; box-sizing: border-box !important;”>

<div style=”color: rgb(255, 255, 255) !important; line-height: 40px !important; font-size: 14px !important;”>View Comments on Dissenter</div>
</a>
</div>

<script>
function openDissenter() {
window.open(“https://dissenter.com/discussion/begin-extension?url=<?php echo get_permalink();?>”, “_blank”, “toolbar=no,scrollbars=yes,resizable=yes,top=0,left=500,width=450,height=800”);
}
