What is New in Firefox 22

Firefox 22 has come with following new features,

WebRTC is now enabled by default

WebRTC means Real-Time Communications, technology that enables audio/video streaming and data sharing between browser clients. WebRTC provides any browser with the ability to share application data and perform teleconferencing peer-to-peer, without the need to install plug-ins or third-party software.

Scaling Options in Windows

Firefox 22 will follow the default display scaling options in Windows OS. If you have the larger display, the text will be rendered larger.

You can also change the Windows Scaling Options (Font size etc.) for Firefox only. To change that,

  • visit about:config page in Firefox and confirm the waring message that you ‘ll be careful.
  • Type or copy  and paster this text  layout.css.devPixelsPerPx in search box to filter out the font scaling values
  • Double Click and change the value. The changes will take effect immediately. You can also reset the value to default there.

HTML5 audio/video playback

In Firefox 22, you can change the playback speed of HTML Video and Audio. This Option only works, if the video player uses native HTML 5 Player. So It won’t work in YouTube HTML 5 mode, since it uses its own HTML 5 Player.
