The Extension.js tool allows for easy development of cross-browser extensions without the need for build configuration. With built-in support for TypeScript, WebAssembly, React, and modern JavaScript, this tool streamlines the process for developers. Users can create a new extension quickly by following simple steps, or kickstart development by utilizing samples from the Chrome Extension Samples repository. Additionally, users can bridge the gap between different browsers by running Mozilla Add-Ons on Edge. With support for a variety of browsers and clear instructions for configuring and running extensions, Extension.js offers a user-friendly solution for extension development. (Word count: 104)
