Firefox Built‑in AI Reverse Agent: A Reverse Engineering Workstation for JS/JSVMP/WASM

Introduction

Firefox‑Reverse is an AI‑enabled reverse‑engineering workstation built into Firefox. It provides a generic JS/JSVMP/WASM/signature analysis environment that uses SpiderMonkey‑level non‑intrusive tracing to recover encrypted parameters as pure algorithms independent of the browser.

Usage

Download the appropriate release, unzip it, and open the AI sidebar. Click the Firefox‑Reverse tool icon (robot/reverse icon) in the right‑hand sidebar to open the Agent panel.

Configure the model: the agent supports DeepSeek, Zhipu GLM, Kimi (Moonshot), MiniMax, Qwen, Claude, OpenAI, or any custom endpoint compatible with the OpenAI/Anthropic API by providing baseUrl, token, and model name.

Two modes

Full automation – provide target interface/parameters and the agent runs end‑to‑end without intervention (suitable for unattended execution).

AI‑assisted – the agent proposes a plan, pauses after each stage, offers direction options, and lets the user approve before proceeding (useful for learning or complex targets).

Example

Describe the target using the following format; the more specific the information, the fewer detours the AI will take:

【站点URL】https://example.com/list          # Page where the target request appears
【接口URL】GET https://example.com/api/v1/list?page=1   # Desired request to reproduce
【目标参数】X‑Sign header (signature). Include any dynamic parameters such as timestamps, device fingerprints, or tokens.
【输出目标】① Black‑box usable version: generate a Node.js script that reproduces the parameters independently.
               ② White‑box pure‑JS version: further reverse to a pure JavaScript implementation without original obfuscated code (optional).

After submitting, the agent captures packets, locates the relevant code, supplements the environment, and validates the result. Generated artifacts—scripts, restored code, and notes—are saved in the work directory assigned to the session.
