Firefox 4.0 might not meet the schedule timings but the Mozilla labs remains stuck to its promise, with introduction of yet another project, Rainbow, which will look towards improvisation of the recording, of audio and video, capabilities of the browser.

Mozilla Labs' Anant Narayanan said, "The Rainbow add-on for Firefox is an early developer prototype that enables web developers to access local video and audio recording capabilities using just a few lines of JavaScript."

He further added:"The add-on generates files encoded in open formats: Theora (for video) and Vorbis (for audio) in an Ogg container. The resulting files are accessible in DOM using HTML5 File APIs, which may be used to upload them to a server".

Experts claim that the sort of addition of features is very much the need of hour, and most of the websites are channeled towards catering the live streaming. YouTube aides to record videos directly from webcam and post it on the site and with the gradual growth of internet platform makes it more interactive and more social.

Mozilla which strongly supports the cause of open standards shall soon be able to offer a way of to access the hardware with standardized and open methodologies. HTML5 offers a platform for this type of functionality. Rainbow comes as an experimental release which is termed as pre-alpha.

The developers are aiming to expand its support towards all platforms such as Windows, Mac and Linux. They also aim to add few of the important features offering live streaming of videos and encode videos in the WebM format.
