The latest version of Firefox, now up to 18, has launched, appearing on the FTP slightly ahead of the official launch date. The installer for Firefox 18 is now available via the front page of the official website and Google Play.
Mozilla has made the change log available. Here's what's new on the desktop version of the browser:
- Support for Retina Display on OSX 10.7 and up
- Preliminary support for WebRTC
- Experience better image quality with our new HTML scaling algorithm
- Performance improvements around tab switching
- Support for new DOM property window.devicePixelRatio
- Improvement in startup time through smart handling of signed extension certificates
- Support for W3C touch events implemented, taking the place of MozTouch events
- Disable insecure content loading on HTTPS pages (62178)
- Improved responsiveness for users on proxies (769764)
The same page includes known issues with the new versions. Some of the more prominent ones include experiencing slower scrolling in the main Gmail window and preventing future updates for Firefox after using Window's System Restore, among others.
Other significant changes to note are the preliminary support for WebRTC, allowing Web pages to access web cameras and microphones for voice chat without the need for a plugin such as Flash, and W3C touch events support in place of MozTouch, bringing the browser to the standard for touch events.
