Firefox fans looking for a major update to the open source Web browser probably will get a final version of it next month.

"We're looking for final ship sometime in June," said Mike Schroepfer, Mozilla's vice president of engineering, in an interview Wednesday. Mozilla, which was spun out of AOL more than 10 years ago, oversees the Firefox programming project.

One of the Firefox's strengths is the broad collection of hundreds of add-ons, but that also means things move more slowly when programmers must update their projects to be compatible with Firefox 3. And that's part of what Mozilla is watching closely as it seeks feedback from the 1.5 million people who have installed the Firefox 3 release candidate 1, which Mozilla issued a few days ago.

"We're in a phase where we're letting add-ons get a chance to update," Schroepfer said. "We like to have RCs (release candidates) out for a while to gather feedback."

More release candidates are possible, he said. With Firefox 2, there were three. "We're in better shape this time, but there's no reason to rush this," he said.

The release candidate is available for download for Windows, Mac OS X, and Linux. If you want to try it out, it's best to read the release notes first, in particular the known issues that could trip you up.

After Mozilla's years-long slow start, Firefox has gained significant market share against its top rival, Microsoft's Internet Explorer. Although the latter still dominates the market, Firefox has helped to reignite the browser wars to an extent: Microsoft is investing more resources in IE development, Apple has brought its own Safari to Windows, and Apple and Google are among those devoting attention to the open source Webkit browser engine project.

Browsers have also become more important as the Internet has begun moving to the more lavish and interactive pages of Web 2.0. For that reason, performance has become a concern: browsers now must execute large amounts of JavaScript code that power-hungry sites such as the office applications of Google Docs and the photo editing of Picnik use.

The Mozilla Foundation has grown significantly over the years. It's set up two subsidiaries, Mozilla Corp. to handle the browser, and the newer Mozilla Messaging group to handle the Thunderbird e-mail software.
