John Lilly, the new CEO of Mozilla Corporation, doesn't want you to pay attention to his new charge. The for-profit arm of the nonprofit Mozilla Foundation produces the Firefox browser and makes money largely by partnering with search engines — that's why the Firefox browser comes with a Google or Yahoo search box built in. "The most successful case for [Mozilla Corporation] will be when the corporation itself is sort of invisible," Lilly writes. Now, why would Lilly want you not to pay attention to his very profitable business — $66.8 million in revenues for the foundation, $56 million of which came from the corporation, in 2006, the most recent year for which it reported results? Perhaps it's because there are questions he'd rather you not ask.

Opera Software, maker of a feature-laden but forgotten Web browser, is complaining to the European Commission about Microsoft's Internet Explorer. It's an old gripe: Opera points out — duh — that IE is bundled with Windows. Opera claims this is illegal and that IE holds back the web with lousy support for standards. This smells like a publicity stunt meant to remind people Opera still exists.

Mozilla is looking for guinea pigs to try out the new version of its browser, Firefox 3 Beta 1. Mozilla calls itself a "foundation" and its slogan is "Good for the Web. Good for the World." But you know better than that. Mozilla topper Mitchell Baker makes $500,000-plus a year and Mozilla's for-profit wing brought in $56 million in revenues last year. In other words, no one should feel obligated by a sense of charity to download the new beta software. Baker & Co. could afford to pay for some actual QA engineers.

Mitchell Baker, who joined Netscape in 1994 and now serves as both chairwoman of the nonprofit Mozilla Foundation and CEO of the for-profit Mozilla Corporation, clocks over a half million in annual salary and benefits, according to a New York Times report. That's more than the $285,000 the foundation, which holds $74 million in assets, says it gave away in grants in 2006. Baker correctly points out that $500K is less than most major Valley CEOs make. I'm pretty sure Wall Street Journal gadget reviewer Walt Mossberg pulls in more. Still, the next time one of you bright-eyed kids writes in to say I owe it to the community to blog up Mozilla and advocate open-source projects? I already gave at the office.

Firefox, we told you, gets a lot of cash from its built-in Google search box. It's one reason why the underdog label should no longer apply to the Mozilla browser. The New York Times is just now picking up on this story, and wonders if all the money will ruin Firefox.

The Mozilla Foundation, the nonprofit behind Firefox, just released its 2006 financial statement. It turns out Moz's for-profit arm is making millions from a deal with Google. 85 percent of its revenue — some $56 million — came from the Google search box that is the default on every Firefox install. Google also provides users for Firefox via a pay-to-download program with Google's AdSense program and the Google Pack — a collection of apps including Google Earth, Adobe Reader, Skype and Firefox. Firefox is generally posited as David against Goliath — Microsoft's Internet Explorer. But really, Firefox is more of the slingshot, wielded by the David of Mountain View as Google and Microsoft fight Browser Wars 2.0. The latest data marks Firefox at 14.9 percent market share against IE's still-dominant 77.9 percent.

Do we need email software anymore? That's the question raised by the turmoil at the Thunderbird project, an open-source effort run by the Mozilla Foundation, also the backers of the popular Firefox Web browser. The foundation runs the Mozilla Corporation as a separate, for-profit business, and spun off a similar company three weeks ago to house Thunderbird. But no sooner than Thunderbird gained its wings did it go into a swan dive. Scott McGregor and David Bienvenu, Thunderbird's only paid developers, are leaving David Ascher to head up a company of none. Neither developer gave a reason for departing the company that Mozilla set up, but Ascher tips his hand that the pair will be starting their own venture. Perhaps a wise move. Why, after all, do we need Thunderbird?
