What browsers does the Website Toolkit work with?

The Website Toolkit is developed using Plone. That supports information access to its pages for all browsers, and as long as the browser isn't parsing and interpreting something it doesn't know how to handle, it's fully functional in any browser. This means you can read content, add content and do all Plone operations from all browsers - although it might be a bit more cumbersome on older browsers.

You will get some additional benefits and ease of use if you have a standards-compliant browser. We have defined four levels of support and will list some of the common browsers according to these levels, so you know what level you can expect in a particular browser.
The Four Levels of Plone browser support

   1. Information Access
          * Browser prerequisites: (X)HTML parsing, optional CSS1 support
          * This enables:
                o All information and functionality accessible by any user agent.
                o Basic CSS 1 visual appearance (where capable)
   2. Graphical Styling
          * Browser prerequisites: CSS2 support
          * This enables:
                o Plones visual appearance
          * Includes Level 1
   3. Extra UI Features
          * Browser prerequisites: Basic DOM2 support
          * This enables:
                o Action menus
                o Date widget
          * Includes Level 1 and Level 2
   4. Advanced UI Features
          * Browser prerequisites: Full DOM2 support, plus the following built-in features:
                o XmlHttpRequest
                o contentEditable/Midas
          * This enables:
                o Visual Editor for content
                o Information retrieval without reloading entire page
          * Includes Level 1, 2 and 3

Website Toolkit does not rely on any external plugins, Flash, Java or similar, but it is possible to use these technologies in Plone.
