Download Mozilla Firefox 22.0 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. Version 22, which will be available on June 25, if all goes well, will handle high-resolution screens under Windows, among other things, and the OS X version will have a download indicator in the dock. Furthermore, WebRTC, announced several times before, will finally be available, which will allow voice and video calls and p2p file exchange, among other things, without the need for separate plug-ins. Below is the provisionally incomplete overview of the improvements that we can expect in version 22.
