Information for website administrators

A rich text editor lets you type formatted text (such as bold, italics) in a form field. They are often used when editing interfaces such as in blogs or forum posts. For instance, TinyMCE is used on platforms such as Prestashop, Drupal, Moodle, concrete5, plone, modx, Mambo, Cascade Server CMS. With Firefox 11, you may see a blank space where text should be and may need to use the HTML view to edit documents.

If you are the administrator of a site with this editor, the simplest thing to do is to update TinyMCE to the latest version (3.4.3 or higher). If you can't do that, you can simply add a line of javascript to the settings to change the way TinyMCE is loaded to avoid this problem. See this post on the TinyMCE forums for more details.
