  Mosaic's open security framework allows for plug-in security modules. Basic Authentication, Digest Authentication, and First Virtual modules come pre-installed.

- Mosaic Software Development Interface (SDI)
  This two-way application programming interface allows other applications to seamlessly interoperate with Mosaic.

  In addition to GIF images, inline JPEG images are now supported.

- Built-in GIF and JPEG Viewers
