Mono, an open source project sponsored by Novell has released Moonlight 0.6 with profile 1.0 and profile 2.0. Moonlight profile 1.0 is based on Silverlight v1.0 and Moonlight profile 2.0 is based on Silverlight v2.0. Silverlight is Microsoft‘s answer to dethrone Adobe’s flash player. Moonlight is Silverlight for Linux.
The above Moonlight versions are test installers, so they are not bug free. Firefox 3 support is known to be buggy, particularly as regards plugin detection from javascript. The funny part is, these are currently built without multimedia support. No video or mp3 playback is enabled on these binaries.
