Zen Browser

Zen Browser is an open-source web browser. It is a desktop web browser built upon the Firefox engine, focusing on modifying the traditional browsing experience to prioritize productivity and user control. The software is designed for users who require a browser that balances the stability of a well established engine with a more flexible and modern interface layout.

The application is deployed as a standalone desktop client. It offers two primary distribution channels to accommodate different user needs: the Release version, which provides a stable experience based on current Firefox versions, and the Twilight version, which utilizes release candidate builds for those who wish to test newer features before they reach the general public. This structure allows users to choose between a conservative update cycle and a more experimental approach to browser stability.

Key features

• Built on the Firefox browser engine
• Split view for simultaneous page viewing
• Enhanced privacy settings
• Extensive interface customization
• Productivity focused layout
• Support for Firefox extensions
• Regular updates based on Firefox release cycles
• Separate stable and release candidate builds

Zen Browser is intended for power users and developers who find the default Firefox interface limiting for multitasking. By implementing split views and a highly customizable workspace, it allows users to manage multiple web applications or documentation pages within a single window without switching tabs. The architecture ensures that it remains compatible with the vast ecosystem of Firefox add-ons, meaning users do not lose access to their existing tools while benefiting from the modified shell. The project is developed openly, with bug tracking and feature requests managed through GitHub Issues and Discussions to ensure community input drives the development roadmap.

It is a productivity oriented fork of Firefox for users seeking a more customizable and efficient browsing environment.
