Open the browser. Notice what's missing.
Right now, somewhere, a person clicks the orange fox and a tab opens. Nothing tracks them by default. No login funnels them toward a single company's account. The thing they just opened is built by an organization with a published list of principles - and the legal structure to be held to it. In 2026 that is a strange and almost defiant arrangement. Most of the internet you touch is owned by three or four companies whose browsers exist to keep you inside their products. Mozilla makes the one that doesn't.
Mozilla Corporation builds Firefox along with a tidy lineup of privacy tools - a VPN, an email masking service, a breach monitor - and maintains MDN Web Docs, the reference web developers quietly keep open in a background tab. Headquartered in San Francisco with roughly 1,800 employees, it is, by the standards of its competitors, small. Google, Apple, and Microsoft each spend more on snacks. And yet Mozilla keeps shipping a browser used by hundreds of millions of people who want one that isn't trying to sell them something.
The web was supposed to belong to everyone.
Here is the tension that runs through everything Mozilla does. A web browser is the most intimate piece of software most people own. It sees every search, every purchase, every late-night question. The companies that make browsers also, by remarkable coincidence, sell ads, phones, and operating systems. A browser, in their hands, is not a neutral window. It is a turnstile.
Mozilla's founders watched this future arrive early. In the late 1990s the browser war was ending with a single winner, and the open standards that made the web a shared commons were at risk of becoming a private hallway. Someone needed to keep a door propped open. The catch: doing that properly meant building world-class software while refusing the business model that funds world-class software everywhere else.
Put people before profit. Then make it structural.
In 1998, Netscape released its browser code to the public and spun off a project called Mozilla - a name stitched together from "Mosaic killer" and "Godzilla," because engineers name things the way engineers name things. Brendan Eich, who had written JavaScript in about ten days a few years earlier, co-founded it alongside Mitchell Baker, the lawyer who would spend the next two decades turning a slogan into an institution.
Their bet was not just idealistic, it was architectural. The Mozilla Foundation is a non-profit. It wholly owns the Mozilla Corporation, a taxable company that can pay competitive salaries and sign billion-dollar deals - but whose profits flow back to the mission, not to shareholders. It is a clever piece of legal plumbing: commercial muscle bolted to a charitable spine. Wilde would have appreciated the irony of incorporating in order to stay pure.

Co-founder of the Mozilla project and creator of JavaScript - the language now running in roughly every browser tab on earth.
Mitchell Baker
Co-founder and longtime Chair and CEO. The architect who turned "open web" from a value into a governance model.
A browser, and the scaffolding around it.
Firefox is the flagship, free and open source on desktop and mobile, built around privacy, speed, and the radical notion that you should be able to change things. Enhanced Tracking Protection runs by default. Facebook Container fences off the thing that wants to follow you. Extensions let people bend the browser to their will rather than the other way around.
Around Firefox, Mozilla built a small constellation of products that treat privacy as a feature you can buy rather than a slogan you have to trust: Mozilla VPN, Firefox Relay for email and phone masking, and Mozilla Monitor for tracking data breaches. And underneath all of it sits MDN Web Docs, which is less a product than public infrastructure - the manual the whole industry reads. Oh, and Rust, the programming language, started life as a Mozilla research project before quietly becoming load-bearing for software everywhere.
Firefox
The open-source browser. Private by default, customizable by design, independent on purpose.
Mozilla VPN
A WireGuard-based VPN with a no-logging policy. Privacy as a subscription, not a promise.
Firefox Relay
Email and phone masking that hides your real address behind aliases to cut spam and tracking.
Mozilla Monitor
Scans for data breaches and helps scrub your details from data-broker sites.
MDN Web Docs
The web developer's reference for HTML, CSS, JavaScript and APIs. Open and global.
Rust (origin)
The systems language born inside Mozilla, now adopted across the software industry.
A quarter century, briefly told.
The spin-off
Netscape opens its source code; the Mozilla project is born, co-founded by Brendan Eich and Mitchell Baker.
Firefox 1.0
Mozilla ships Firefox to the public and starts winning the open web a real seat at the table.
The Corporation
Mozilla Corporation is formed as a for-profit subsidiary wholly owned by the non-profit Foundation.
Rust appears
A Mozilla research project becomes the Rust language, later one of the most loved tools in software.
Quantum
Firefox Quantum rebuilds the engine for speed, a statement that independence need not mean slow.
Privacy as a product line
Mozilla VPN, Firefox Relay, and Monitor turn the mission into things you can subscribe to.
New CEO, AI ahead
Anthony Enzor-DeMeo becomes CEO; Firefox is set to become a "modern AI browser" with optional, choice-first AI.
Small budget. Outsized footprint.
The numbers are lopsided in a way Mozilla seems to enjoy. It competes with the most valuable companies in history using a fraction of their headcount, and it does so while giving most of its work away. The case for Mozilla isn't that it's the biggest. It's that it's the one keeping the others honest.
Where the money comes from
The partnerships tell the rest of the story. A long-running search-default agreement with Google has historically funded the lights. The Mozilla Foundation steers the mission from above. And ongoing work inside web-standards bodies - W3C, WHATWG, ECMA - means Mozilla helps decide what the web itself is allowed to do, not just how to browse it.
The search-default deal that has long been Mozilla's largest revenue source - and its most-debated dependency.
Mozilla Foundation
The non-profit parent that owns the Corporation and guards the public-benefit mission.
Standards bodies
W3C, WHATWG and ECMA - where Mozilla helps write the rules of the open web, JavaScript included.
The manifesto is a real document.
Plenty of companies have values. Mozilla wrote its down, made it public, and built a legal structure that forces it to mean something. The Mozilla Manifesto treats the internet as a global public resource and individual privacy as non-optional. It reads like a constitution because, functionally, it is one - the thing the whole operation can be measured against when convenient quarterly logic suggests cutting a corner.
That mission now points squarely at AI. Mozilla's bet, articulated by its new leadership, is that artificial intelligence belongs in the browser - but on the user's terms. Optional. Model-choice. Privacy-aware. The iOS feature "Shake to Summarise" was named one of TIME's best inventions of 2025, a small proof that "ethical" and "useful" need not be opposites.
The next turnstile is being built now.
Every shift in computing creates a new place to put a turnstile. The browser war gave us one. Mobile gave us another. AI is building the next, and the companies pouring billions into it are not, as a rule, known for putting people before profit. Whether the AI layer of the internet ends up open or enclosed is being decided right now, mostly by people who profit from enclosure.
This is where Mozilla's strange structure earns its keep. An organization that can sign commercial deals but cannot be bought, that ships software but answers to a manifesto, is exactly the sort of thing you'd want at the table when the next decade of the web gets drawn up. It may be outspent. It is rarely outflanked on principle.
Five facts about Mozilla.
"Mozilla" = "Mosaic killer" + "Godzilla." The original mascot was a green monster meant to slay the Mosaic browser.
JavaScript in ~10 days. Co-founder Brendan Eich wrote the language in 1995 in a famously short sprint.
Rust grew up here. Born as a Mozilla side project, it now tops "most loved language" developer surveys.
A non-profit owns the company. Profit from Firefox flows back to the mission, not to shareholders.
The principles are public. The Mozilla Manifesto is a real document anyone can read - and hold them to.
Open the browser. Notice what's still there.
Click the orange fox again. The tab opens the same way it did at the top of this page - quietly, without a sales pitch, without following you out the door. That ordinariness is the whole achievement. It took a manifesto, a non-profit, a for-profit, twenty-five years, a programming language or two, and a stubborn refusal to take the easy money to make "a browser that just works for you" feel normal.
The web didn't stay open by accident. Someone propped the door. They're still standing there.
