Google Chrome and Firefox can now communicate by using standard technologies such as the Opus and VP8 codecs for audio and video, DTLS-SRTP for encryption, and ICE for networking.
"The new communication between the two browser was made via WebRTC technologies to bring clear crisp voice, sharp high-definition (HD) video and low-delay communication to the web browser," Google said.
To try this yourself, you'll need desktop Chrome 25 Beta and Firefox Nightly for Desktop.
In Firefox, you'll need to go to about:config and set the media.peerconnection.enabled pref to "true". Then head over to the WebRTC demo site and start calling.

Update 02/06: Google also launched today, a new Chrome Experiment called "Find Your Way to Oz" built with the WebGL and CSS3 technologies and lets you compose your own music, play with a fun photo booth and create your own movie with a zoetrope.
The path to Oz also involves confronting an ominous tornado; surviving it completes the journey, enabling fans of the movie to watch an exclusive unreleased clip from the film.
"It's enhanced by rich audio effects thanks to the Web Audio API. The photo booth and zoetrope were built using the getUserMedia feature of WebRTC, which grants webpages access to your computer's camera and microphone (with your permission)," Google stated.
