Mozilla Releases Firefox 18 with Retina Display Support

On Tuesday, Mozilla released Firefox 18 for Mac, Windows, Linux and Android. The new version brings Retina display support for Macs and a new JavaScript compiler called "IonMonkey" that Mozilla says will speed up Web apps and games by 25 percent.

Also included, according to Mozilla are: performance enhancements in tab switching, better imaging with a new HTML scaling algorithm and preliminary support for WebRTC.

The Android version will provide a warning when the user attempts to access a Web site that may be harmful and also supports Do No Track.

Current users should see the update available in the "About Firefox" window. As always, a direct download is available.
