Mozilla to Release Firefox 3.0 in June

Next month, after three years of development and six months of public testing, Mozilla, the insurgent browser developer that rose from the ashes of Netscape, will release Firefox 3.0. It will feature a few tricks that could change the way people organize and find the sites they visit most frequently.

Not to be outdone, Microsoft recently took the wraps off the first public test version of the latest edition of Internet Explorer, which is used by about 75 percent of all computer owners, according to Net Applications, a market share tracking firm. The finished version of Internet Explorer 8 could be released by the end of the year and is expected to have additional features.

Even Apple, which once politely kept its Safari browser within the confines of its own devices, is making a somewhat controversial push to get it onto the computers of people who use Windows PCs.

In other words, the browser war — the skirmish that landed Microsoft in antitrust trouble in the ’90s — is heating up again.

America Online, which acquired Netscape, spun off the nonprofit Mozilla Foundation in 2003. Its Firefox browser soon inspired an open-source movement backed by computer enthusiasts. Early versions of Firefox introduced features like a built-in pop-up blocker to kill ads, and tabbed browsing, which lets users toggle between Web windows.

Firefox now has 170 million users around the world and an 18 percent share of the browser market, according to Net Applications. That is especially impressive given that most of its users have made the active choice to download the software, while Internet Explorer is installed on most PCs at the factory.

In addition to giving Microsoft a kick in its competitive pants, Firefox has also reinforced for the high-tech industry the financial and strategic value of the browser. In 2004, Google struck a deal with Mozilla to include a Google search box tucked into a corner of the Firefox browser. According to Mozilla’s most recent tax documents, in 2006 Google paid Mozilla $65 million for the resulting traffic to its search listings.

With tasks like e-mail and word processing now migrating from the PC to the Internet, analysts and industry players think the browser will soon become even more valuable and strategically important.

“People in the industry foresee a time in which for many people, the only thing they’ll need on a computer is a browser,” said Mitch Kapor, the software pioneer who now sits on the board of the Mozilla Foundation and has created a start-up, FoxMarks, that is developing a tool to synchronize bookmarks between computers. “The browser is just extraordinarily strategic.”
