+# Figma Windows UA Spoofer (Chrome + Firefox)
+
+`figma.com` / `*.figma.com`에서만 User-Agent를 Windows로 바꾸고,
+페이지 JS의 `navigator.userAgent`, `navigator.platform`도 Windows 값으로 오버라이드합니다.
+
+## 빠른 사용
+
+### Chrome / Edge
+
+1. `chrome://extensions` (Edge: `edge://extensions`) 접속
+2. 개발자 모드 ON
+3. 압축해제된 확장 프로그램 로드
+4. 프로젝트 폴더 선택
+
+### Firefox unsigned 빌드
+
+```bash
+./build-firefox.sh
+```
+
+- 출력: `dist/figma-windows-ua-firefox-unsigned.xpi`
+- 개발/테스트용 unsigned 패키지
+
+### Firefox 서명 빌드 (실사용)
+
+1. AMO(Add-ons Mozilla)에서 API Key/Secret 발급
+2. `.env`에 값 저장 (자동 로드)
+
+```dotenv
+AMO_JWT_ISSUER="<your-api-key>"
+AMO_JWT_SECRET="<your-api-secret>"
+```
+
+3. Nix로 서명 실행 (추천)
+
+```bash
+nix run .#sign-firefox
+```
+
+- 출력: `dist/signed/*.xpi` (서명 완료)
+
+## Firefox 설치
+
+- 임시 로드: `about:debugging#/runtime/this-firefox` → 임시 부가 기능 로드 → `dist/firefox/manifest.json`
+- 실제 배포/설치: `dist/signed/*.xpi` 사용
+
+## 확인
+
+`figma.com`에서 콘솔 실행:
+
+```js
+navigator.userAgent
+navigator.platform
+navigator.userAgentData?.platform
+```
+
+Windows 계열 값이면 정상입니다.
