The flashiest news out of the Firefox 34 release may be Mozilla’s switch from Google to Yahoo as its default search engine, but the far more significant news is a WebRTC client built directly into the browser.

The first Firefox 34 Beta release including a WebRTC client debuted back in September, but the official Firefox 34 release packs new features and the client’s first name: Firefox Hello. The “Firefox Hello” WebRTC-powered chat tool allows Firefox users to engage in audio and video chats with others directly in their browsers.

Firefox Hello is powered by the TokBox OpenTok real-time communications platform (a subsidiary of Spanish telecommunications company Telefonica). The WebRTC client’s big debut in Firefox 34 comes with new call options with optional Firefox account integration to sync contact lists.

WebRTC technologies have been in development for years, a pet project of sorts of the World Wide Web Consortium. The international organization has worked to advance the technology while skirting the issue of competing HTML5 video codec standards that had held up the adoption process. As a result, WebRTC specifications are now enabled in some form in most major browsers. HTML5 is now a W3C recommendation, the group’s highest stamp of approval.

Given the wider implementation of WebRTC, Firefox is not the only browser pursuing WebRTC integration. Google is in the process of adding WebRTC to Chrome; the Opera and Firefox Nightly browsers have varying levels of real-time communication functionality; and even Internet Explorer is in the early stages of WebRTC exploration. The only major browser with no WebRTC functionality whatsoever is Safari.

Elsewhere in Firefox 34, Mozilla has implemented the ECMAScript 6 weak set; disabled the vulnerable SSL 3.0 encryption; and rolled out its new WebIDE developer tool for Firefox OS app creation, editing and management.

As for Firefox Hello, the WebRTC client is temporarily enabled in only a random 10% of browsers to prevent initial system overload. The full breakdown of new features is available in the Firefox 34 release notes.
