What’s New in Firefox 3.5:
Firefox 3.5 makes surfing the Web easier and more enjoyable with
exciting new features and platform updates that allow Web developers to
create the next generation of Web content. Native support for open
video and audio, private browsing, and support for the newest Web
technologies will enable richer, more interactive online experiences.
Performance. Firefox 3.5 includes the powerful new
TraceMonkey JavaScript engine, which delivers unprecedented performance
with today’s complex Web applications. Firefox 3.5 is more than two
times faster than Firefox 3 and ten times faster than Firefox 2.
Open Video and Audio. Enjoy video and audio content
from within your browser, without the need for plugins. Video is a
vital part of the modern Web, whether it’s used to communicate,
educate, or entertain. Firefox 3.5 delivers the first native
integration of audio and video directly into the browser. Now everyone
can easily watch open format Ogg Theora videos.
Web developers can use these technologies to design pages that
interact with video content in new and exciting ways, offering richer
interactive experiences beyond controlling playback and volume.
Privacy Controls. Firefox 3.5 includes features designed to protect your privacy online and provide greater control over your personal data.
While using the new Private Browsing mode in Firefox 3.5, nothing
you encounter on the Web will be stored from that moment on during your
browsing session. Unique to Firefox 3.5, the new Forget this Site
feature can remove every trace of a site from your browser. If you want
to remove all private data or activity from the past few hours, Clear
Recent History, another Firefox-only feature, gives you full control
over what stays and what goes.
Location Aware Browsing. Location Aware Browsing
saves you time by allowing websites to ask you where you are located.
If you choose to share your location with a website, it can use that
information to find nearby points of interest and return additional,
useful data like maps of your area. It’s all optional – Firefox doesn’t
share your location without your permission.
