In a posting on Mozilla.org's Web site last week, the group said it is "very close to the finish line for 1.0. We look forward to celebrating Mozilla 1.0 shortly!"
It has been more than four years since Web browser vendor Netscape Communications released its source code in early 1998 and created the Mozilla.org open-source community to work on the development of future browsers. Version 1.0, which has yet to be finalised, will soon be available to download to allow wider testing and feedback before a final Version 1.0 release or a second release candidate is ready, according to the group.
Mitchell Baker, a spokeswoman for Mozilla.org, said no date has yet been set for a final release.
Last month, America Online said it was testing several open-source software products to run various parts of its Internet service, a move that could herald a shift from Microsoft's Web-browsing software.
The test version of the AOL software is powered by what is known as the Gecko rendering engine, which is the technology responsible for allowing Web pages to be displayed in a browser. Gecko powers the latest versions of the Netscape browser and is at the core of Mozilla.
