No Embedding the real Firefox JavaScript engine (SpiderMonkey) and networking stack (Necko) headlessly in a Python binding requires deep C++ browser-engine and build-system expertise that vibe coding cannot substitute for.
What it would actually take: The project requires building Mozilla's SpiderMonkey and Necko from source, writing C/C++ glue exposed to Python via FFI, and maintaining compatibility with upstream Firefox internals. Expertise needed is browser engine internals, C++ build systems, and ongoing rebasing against a large moving codebase.
