Our take
Mozilla creates and manages a range of free-to-use software products. Their most well-known product is Firefox, the fourth most popular internet browser in the world. Mozilla is a not-for-profit with a focus on promoting online privacy. The company has a published manifesto outlining its commitment to keeping a balance between commercial profit and public benefit.
The companies other products include Bugzilla, a bug management platform, and Pocket, an award-winning digital content filing service. In direct odds with Google, Mozilla has recently launched a new product Mozilla VPN. The VPN or virtual private network enables users to browse the internet without being tracked. Companies such as Google rely on tracking user behavior online to target them with advertising.
Mozilla was also instrumental in creating the programming language Rust, which is admired for its brevity. Rust uses roughly half the amount of code as C++ to produce the same results.
