Developer runs full Firefox browser compiled entirely in WebAssembly

A developer has compiled the entire Firefox browser — including the Gecko rendering engine, all UI components, and the SpiderMonkey JavaScript engine — into WebAssembly and run it inside a canvas element in the browser. The project features end-to-end encryption via the WISP protocol (TCP over WebSocket) and an experimental WASM-to-JS JIT compiler. The creator notes it was a fun experiment pushing WebAssembly's limits, recommending the lighter browser.js project for practical use.
