Mozilla

Mozilla is a global open-source software organization dedicated to promoting openness, innovation, and opportunity on the internet. Founded in 1998, it began when Netscape Communications Corporation released its browser suite source code, allowing programmers worldwide to contribute. Mozilla operates through two main entities: the Mozilla Foundation, a non-profit organization, and the Mozilla Corporation, a subsidiary that manages commercial operations. Mozilla's flagship product is the Firefox browser, a free and open-source web browser that emphasizes user choice and control. Other notable products include Thunderbird, an email client, and the Mozilla Developer Center, which provides resources for web standards and development. Mozilla also supports community initiatives, offering grants for web accessibility improvements and exploring new technology areas like Mozilla.ai. The organization thrives on collaboration, with thousands of volunteers contributing to its projects and initiatives globally.
