"The new Firefox channel switcher lets users move between Firefox Aurora, beta and release channels to test features at various levels of development, quality and polish," said Mozilla.
The Firefox Aurora development channel is designed to support more frequent releases. The beta version of the web browser was previously tested in Firefox's "Aurora" development channel for five weeks.
