README

dsh-browser-firefox

DeepSeek Harness（dsh）的 Firefox 浏览器操作 bridge 插件。与 Firefox 扩展「DSH 浏览器助手」配套使用，让模型读取并操作你正在使用的 Firefox 标签页（登录态保留、后台静默新开标签页、会话级标签页组）。

完整文档与源码：https://github.com/tuojc/dsh-browser-firefox

安装

dsh plugin --profile web add dsh-browser-firefox@latest

安装后重启 dsh web 生效。首次启动会在 ~/.dsh/ext-bridge-token 生成 bearer token（0600 权限）。

配套扩展与 token

  1. 从 AMO 安装 Firefox 扩展：DSH 浏览器助手。
  2. 打开扩展侧边栏 → 设置 → 把 ~/.dsh/ext-bridge-token 的内容粘贴到 Token 一栏 → 保存并连接（桥地址留空，自动探测本机 3080/3081/3090 端口）。

Firefox 的 moz-extension:// Origin 是每次安装随机生成的 UUID，不构成身份边界，因此 0.3.1 起 Firefox 客户端必须出示 token（与上游 Lum1104/dsh-browser 同步的安全收紧）。

提供的工具

browser_snapshot（结构化文本快照）、browser_click、browser_type、browser_press、browser_scroll、browser_navigate（后台新标签页）、browser_back / browser_forward / browser_reload、browser_get_text、browser_wait、browser_evaluate、browser_screenshot（视觉兜底）、browser_clear_screenshots、browser_list_tabs。

纯文本集成：页面渲染为带编号交互元素清单的文本；截图只保存为文件交给视觉工具，不进入模型上下文。
