Extension.js 3: Browser Extension Development Framework

A new tool is streamlining the development of cross-browser extensions by eliminating the need for manual build configuration. This innovative solution allows developers to create, build, and preview browser extensions for multiple platforms using a unified workflow, significantly reducing setup time and complexity.

The article highlights how the tool’s integrated approach enables seamless development across browsers like Chrome, Firefox, and Edge. With features such as live preview and automated builds, developers can focus on writing code rather than managing configuration files or troubleshooting compatibility issues.

Available as an open-source project on GitHub, this tool is poised to accelerate extension development and foster greater consistency across browser ecosystems.
