HTML Area is no longer developed/supported: http://www.dynarch.com/projects/htmlarea/
In addition Firefox 15 and up are going to display an "unsupported gecko" warning due to the user agent in firefox changing from Gecko/20100101 to Gecko/geckversion
http://xinha.webfactional.com/ is considered the successor of HTMLArea, and does not have this issue.
