This count is not comparable across projects: each project's automation decides which of these events a person emits. How this is counted.

Detailed Description

Zen Browser is a Firefox-based web browser designed to enhance productivity and create a calmer browsing experience.

The project addresses the need for a more focused and efficient web browser by building on Firefox's foundation and adding productivity-focused features. Rather than starting from scratch, the approach leverages Firefox's rendering engine and security infrastructure while customizing the interface and behavior to reduce distractions and support focused work.

Developers and users seeking an alternative to mainstream browsers with an emphasis on productivity should consider Zen. It suits anyone frustrated with attention-fragmenting design in standard browsers and wanting a more intentional browsing experience. The project maintains both a stable release channel built on current Firefox versions and a Twilight channel tracking Firefox release candidates for those wanting to test newer features earlier.

The project maintains active engagement with its community through GitHub Issues for bug reports and GitHub Discussions for feature requests, with documented contribution guidelines for those wishing to participate. The codebase is open source and welcomes community contributions, supported by established partnerships that provide backing and resources for ongoing development.
