One of our admins started experiencing a weird issue when editing a post. When the link button is clicked inside the post editor in visual mode, the box appears with the content inside, but it is grayed out and nothing is clickable. This is only currently happening in Firefox. I already instructed the admin to clear the cache, logout/login, restart the computer, etc, but nothing has seemed to do the trick. Any ideas?
