The latest beta release of the Mozilla Firefox Web browser, based on the
Gecko 1.9.1 rendering platform, contains a number of new features, such as availability
in 70 languages, privacy tools including a Private Browsing Mode, improvements
to the Gecko layout engine, such as speculative parsing for faster content
rendering, and support for Web technologies including HTML5 and elements.
"This milestone is focused on testing the core functionality provided
by many new features and changes to the platform scheduled for Firefox 3,"
Mozilla said in a blog post. "Testers can download Firefox 3.5 Beta 4
builds for Windows, Mac OS X and Linux in 64 different languages. Developers
should also read the Firefox 3.5 for Developers article on the Mozilla
Developer Center."
Beta 4 will be followed by a Firefox release candidate, which in turn will
be followed by the final release of Firefox 3.5. Even before reaching this
point, however, the updated Firefox has gone through a number of previous
versions.
On March 12, Mozilla
released its Firefox 3.1 Beta 3 Web browser, also based on the Gecko 1.9.1
rendering platform, and featuring improvements to Web worker thread support,
increased stability with the TraceMonkey JavaScript engine and the World Wide
Web Consortium Geolocation API.
Originally released in 2004, Firefox is the second-most popular Web browser
in terms of market share, lagging behind Microsoft's
Internet Explorer in number of total users. On the other hand, Firefox maintains
a comfortable lead in U.S.
market share over Apple Safari and Google
Chrome.
