Download Mozilla Firefox 34.0 Beta

As we are used to from Mozilla, the first beta release of the next version has already appeared shortly after the release of a stable version of the Firefox web browser. In version 34, which should be available on November 25, if all goes well, WebRTC functionality, among other things, has now crystallized to the point where a chat client called Firefox Hello has been added, which allows voice and video calls to be made. Below is the still incomplete overview of the improvements that we can expect in version 34.
