Mozilla engineers are working hard to make the Firefox browser supports FLAC. According to current estimates, Firefox 51 is scheduled for the end of a stable version of the browser released next year will be the first formal support FLAC. FLAC is the Free Lossless Audio Codec acronym, but it is an open source lossless compressed audio codec. FLAC allows music lovers with a smaller file size to listen to the original audio data, even if the current FLAC file size exceeds several times the size of an ordinary MP3 file.
Currently Mozilla engineers have begun to support FLAC embedded in the main Firefox code base. Firefox browser will be the top five browser (Firefox, IE / EDGE, Safari, Opera) among the first to support FLAC browser.
Currently, only music streaming services such as SoundCloud and Tidal provide users FLAC version, and requires the user equipment or software support FLAC playback. After the Mozilla Firefox browser supports FLAC, FLAC files will automatically play in your browser, just like ordinary play MP3, WAV and other audio file as.
Currently, Nightly version of Firefox has been an informal support to FLAC.
