git clone https://github.com/cutetailbud/ff-ruyijs.git
Python library that runs site JavaScript through a headless SpiderMonkey and Necko engine from Firefox 159, with no window or renderer.
Why you might care
Aimed at scraping, JS reverse engineering, and getting past bot checks, it runs the genuine Firefox JS engine and network stack instead of an imitation. Each Context is an isolated process with its own proxy, and it can replay captured flows offline. Windows x64 only, with Python 3.10+; the wheel bundles the runtime.
