I came across a website for a court clerk. The site looks fine on Internet Explorer, but is absolutely unreadable on Firefox or Safari. For some reason, the designer wanted to use Edwardian Script, which was specified in a broken font tag. Internet Explorer ignored the broken tag, so the website was readable. However, Firefox and Safari recognized the tag, and applied the Edwardian Script to most of the text. Yikes. Save the script for wedding invitations. Use Arial, or Helvetica, if you curse the scourge of Arial.
