NOTE: Karmanaut no longer supports the Cosmo Player.
Cosmo Player was a NPAPI plugin for viewing 3D (VRML worlds; suffix *.wrl; MIME types model/vrml and x-world/x-vrml) in browsers. K-Meleon can still run the Cosmo Player plugin. If you download the installer, it will ask you whether you want to use it as a standalone browser or with other (unsupported) browser. Choose the second option (unsupported browser) and define your K-Meleon plugins directory in the installation. After that, the following files will be in your K-Meleon Plugins directory:
