Seals at the footer being incorrectly displayed on Firefox

Hi!

If you access my site through Firefox and Chrome, you'll see that on Firefox the GoDaddy SSH seal isn't being displayed; also, the seals aren't being displayed in an aligned manner as they are on Chrome:

Here's the whole content of my child theme's footer.php:

If necessary, I've sent my credentials with Adam's name on it a couple of days ago.

Thanks. :slight_smile:
