"The Firefox of today is significantly better than the Firefox of a year ago in every way," wrote Mozilla vice president of engineering Johnathan Nightingale in a recent blog post. There are good cases to be made for that statement, including the browser’s better security, faster startup, a social network API, and more efficient memory use.
The Android version of Firefox has also been updated with search suggestions and new protections against phishing and malware.
The new version also adds preliminary support for WebRTC, which among other things, allows Web pages to access a computer’s webcam and microphone without the need for plugins such as Adobe Flash or Microsoft SilverLight. Other performance improvements and new standards support show up in Firefox 18, including support for W3C touch eventsâ€”very useful on tablets. According to Mozilla’s release notes, startup time has been improved by "smart handling of signed extension certificates."
