Mozilla Firefox Significantly Reduces Memory Use to Make Web Browsing Faster


Mozilla, a global, non-profit organization dedicated to making the Web better, today released an update to Firefox for Windows, Mac and Linux. Mozilla Firefox provides a speedy Web browsing experience for users and new tools to help developers create faster websites and Web apps.

Firefox manages memory more efficiently to deliver a nimble Web browsing experience. Users will notice Firefox is faster at opening new tabs, clicking on menu items and buttons on websites. Heavy Internet users will enjoy enhanced performance when lots of tabs are open and during long Web browsing sessions that last hours or even days.

New tools in Firefox make it easier for developers to build snappy Web experiences for users. A new version of hardware-accelerated Canvas speeds up HTML5 animations and games in Firefox. This allows developers to build more compelling and interactive Web experiences like Angry Birds or Runfield.

Firefox now supports the W3C navigation timing spec API so developers can measure page load time and website navigation against bandwidth speed, website traffic and other factors. This API allows developers to test user experiences remotely and easily and quickly optimize websites and Web apps for different types of users.

To help improve future versions of Firefox, users can opt in to Telemetry. Telemetry is a tool built on Mozilla Privacy Principles that allows users to provide anonymous browser performance data in a private and secure way that they control.
