+## 🚨 Problemas Comunes
+
+### "Add-on could not be installed because it is not signed" (Firefox)
+
+**Causa:** Firefox Release no permite extensiones sin firma.
+
+**Soluciones:**
+1. ✅ **Carga temporal** (se borra al cerrar):
+   - `about:debugging` → "Cargar complemento temporal"
+   
+2. ✅ **Firefox Developer Edition** (permanente):
+   - Descargar: https://www.mozilla.org/firefox/developer/
+   - `about:config` → `xpinstall.signatures.required` → `false`
+   
+3. ✅ **Firmar con AMO** (para distribución):
+   ```bash
+   # Obtener credenciales: https://addons.mozilla.org/developers/addon/api/key/
+   # Configurar en: private-keys/firefox-amo-credentials.json
+   ./build.sh --sign
+   ```
+
+### "Manifest version 2 is deprecated/not supported" (Chrome)
+
+**Causa:** Chrome 127+ bloqueó Manifest v2 (junio 2024).
+
+**Soluciones:**
+1. ✅ **Usa Firefox** (mejor opción):
+   - Firefox soporta Manifest v2 indefinidamente
+   - Ver instrucciones arriba
+   
+2. ✅ **Usa Edge o Brave** (temporal):
+   - Soportan Manifest v2 hasta ~2025-2026
+   - Instalar en modo desarrollador
+   
+3. ❌ **Migrar a Manifest v3**:
+   - No disponible aún (requiere reescritura)
+   - Incompatible con sql.js (necesita `'unsafe-eval'`)

+# Guía de Firma de Extensiones
+
+Esta guía explica cómo firmar las extensiones de Classic Add-ons Archive para Firefox y Chrome.
+
+## 🔐 ¿Por qué firmar?
+
+- **Firefox**: Las extensiones firmadas pueden distribuirse fuera de AMO
+- **Chrome**: La firma genera un ID consistente y permite actualizaciones
+- **Seguridad**: Los usuarios pueden verificar la autenticidad
+- **Profesional**: Distribución en stores oficiales
+
+## 📋 Requisitos Previos
+
+### Software necesario
+
+```bash
+# Instalar Node.js y npm (si no lo tienes)
+sudo apt install nodejs npm   # Debian/Ubuntu
+# o
+brew install node             # macOS
+
+# Instalar dependencias del proyecto (incluye web-ext)
+npm install
+
+# Para Chrome: openssl (generalmente ya instalado)
+openssl version
+```
+
+**Nota**: web-ext se instala automáticamente como dependencia local, no necesitas instalarlo globalmente.
+
+### Permisos de ejecución
+
+```bash
+chmod +x scripts/generate-keys.sh
+chmod +x build.sh
+```
+
+## 🔑 Paso 1: Generar Claves
+
+### Generación automática
+
+```bash
+cd /home/ale/projects/firefox/ca-archive
+./scripts/generate-keys.sh
+```
+
+Este script genera:
+- **Chrome**: Clave privada RSA 2048-bit (`private-keys/chrome-extension.pem`)
+- **Chrome**: Extension ID calculado
+- **Firefox**: Plantilla de credenciales AMO
+
+### Generación manual (alternativa)
+
+**Para Chrome:**
+```bash
+mkdir -p private-keys
+openssl genrsa -out private-keys/chrome-extension.pem 2048
+```
+
+**Para Firefox:**
+Crea `private-keys/firefox-amo-credentials.json`:
+```json
+{
+  "web-ext": {
+    "sign": {
+      "apiKey": "user:12345678:123",
+      "apiSecret": "tu-secret-aqui",
+      "id": "ca-archive@Off.JustOff",
+      "channel": "unlisted"
+    }
+  }
+}
+```
+
+## 🦊 Paso 2: Configurar Credenciales de Firefox (AMO)
+
+### Obtener credenciales AMO
+
+1. **Inicia sesión** en https://addons.mozilla.org
+
+2. **Ve a API Keys**: https://addons.mozilla.org/developers/addon/api/key/
+
+3. **Genera credenciales**:
+   - Click en "Generate new credentials"
+   - Copia el **JWT issuer** (API Key)
+   - Copia el **JWT secret** (API Secret)
+
+4. **Edita el archivo de credenciales**:
+   ```bash
+   nano private-keys/firefox-amo-credentials.json
+   ```
+
+5. **Agrega tus credenciales**:
+   ```json
+   {
+     "web-ext": {
+       "sign": {
+         "apiKey": "user:12345678:456",
+         "apiSecret": "1a2b3c4d5e6f7g8h9i0j...",
+         "channel": "unlisted"
+       }
+     }
+   }
+   ```
+
+**Nota importante**: El ID de la extensión (`ca-archive@Off.JustOff`) se lee automáticamente de `manifest.json`, no es necesario incluirlo en las credenciales.
+
+### Tipos de canal (channel)
+
+- **`unlisted`**: No aparece en búsquedas de AMO, distribución externa
+- **`listed`**: Aparece en AMO, revisión más estricta
+
+**Recomendado**: Usar `unlisted` para desarrollo y `listed` para producción.
+
+## 🏗️ Paso 3: Construir y Firmar
+
+### Firmar ambas versiones
+
+```bash
+./build.sh --sign
+```
+
+Esto:
+1. Construye paquetes ZIP sin firmar
+2. Firma el paquete de Firefox con AMO
+3. Firma el paquete de Chrome con tu clave privada
+4. Genera archivos `.xpi` (Firefox) y `.crx` (Chrome)
+
+### Firmar solo Firefox
+
+```bash
+./build.sh --sign-firefox
+```
+
+### Firmar solo Chrome
+
+```bash
+./build.sh --sign-chrome
+```
+
+### Usando npm scripts
+
+```bash
+# Generar claves
+npm run keys:generate
+
+# Construir sin firmar
+npm run build
+
+# Construir y firmar todo
+npm run build:sign
+
+# Firmar solo Firefox
+npm run build:sign-firefox
+
+# Firmar solo Chrome
+npm run build:sign-chrome
+```
+
+## 📦 Archivos Generados
+
+Después de la firma encontrarás en `dist/`:
+
+### Firefox
+- `ca-archive-3.0.0.xpi` - Paquete sin firmar
+- `ca-archive-3.0.0-an+fx.xpi` - Paquete firmado por AMO
+- `firefox-sign.log` - Log del proceso de firma
+
+### Chrome
+- `ca-archive-3.0.0-chrome.zip` - Paquete ZIP sin firmar
+- `ca-archive-3.0.0-chrome.crx` - Paquete firmado
+- `chrome-extension-id.txt` - ID de la extensión
+- `ca-archive-3.0.0-chrome.crx.sha256` - Hash de verificación
+
+## 🔍 Verificar Firma
+
+### Firefox
+
+```bash
+# Verificar que es un ZIP válido
+unzip -t dist/ca-archive-*.xpi
+
+# Ver metadatos (requiere web-ext)
+web-ext lint --source-dir=. --self-hosted
+```
+
+### Chrome
+
+```bash
+# Verificar hash SHA256
+sha256sum -c dist/ca-archive-*-chrome.crx.sha256
+
+# Ver Extension ID
+cat dist/chrome-extension-id.txt
+```
+
+## 🚀 Distribución
+
+### Firefox
+
+**Opción 1: AMO (Recomendado para usuarios finales)**
+
+1. Ve a: https://addons.mozilla.org/developers/
+2. Click en "Submit a New Add-on"
+3. Sube el archivo `.xpi` firmado
+4. Completa información y submit para revisión
+
+**Opción 2: Self-hosted (para desarrollo)**
+
+1. Sube el `.xpi` firmado a tu servidor
+2. Usuarios pueden instalarlo desde: `https://tu-servidor.com/ca-archive.xpi`
+3. Firefox verificará la firma automáticamente
+
+### Chrome
+
+**Opción 1: Chrome Web Store (Recomendado)**
+
+1. Ve a: https://chrome.google.com/webstore/devconsole
+2. Click en "New Item"
+3. Sube el archivo **`.zip`** (NO el .crx)
+4. Completa información y publica
+
+**Nota**: Chrome Web Store firma automáticamente, no subas el .crx.
+
+**Opción 2: Enterprise distribution (.crx)**
+
+1. Distribuye el archivo `.crx` firmado
+2. Los usuarios deben agregarlo manualmente
+3. Requiere políticas empresariales habilitadas
+
+## 🔐 Seguridad de las Claves
+
+### ⚠️ IMPORTANTE: Protege tus claves
+
+```bash
+# Permisos seguros
+chmod 600 private-keys/chrome-extension.pem
+chmod 600 private-keys/firefox-amo-credentials.json
+chmod 700 private-keys/
+
+# Verificar que están en .gitignore
+git status private-keys/  # Debe decir "ignored"
+```
+
+### Backup de claves
+
+```bash
+# Hacer backup cifrado
+tar czf ca-archive-keys-backup.tar.gz private-keys/
+gpg -c ca-archive-keys-backup.tar.gz
+rm ca-archive-keys-backup.tar.gz
+
+# Guarda ca-archive-keys-backup.tar.gz.gpg en lugar seguro
+```
+
+### Restaurar backup
+
+```bash
+gpg -d ca-archive-keys-backup.tar.gz.gpg > ca-archive-keys-backup.tar.gz
+tar xzf ca-archive-keys-backup.tar.gz
+```
+
+### ¿Qué hacer si pierdes las claves?
+
+**Chrome:**
+- El Extension ID cambiará
+- Los usuarios verán una extensión "nueva"
+- Perderás valoraciones/estadísticas
+
+**Firefox:**
+- Puedes generar nuevas credenciales AMO
+- El ID de la extensión se mantiene (está en manifest.json)
+
+## 🐛 Troubleshooting
+
+### Error: "Cannot set custom ID ... because manifest.json declares ID"
+
+**Causa**: El archivo de credenciales incluye un campo `"id"` que ya está en manifest.json
+
+**Solución**:
+Edita `private-keys/firefox-amo-credentials.json` y elimina la línea con `"id"`:
+```json
+{
+  "web-ext": {
+    "sign": {
+      "apiKey": "user:12345678:123",
+      "apiSecret": "tu-secret-aqui",
+      "channel": "unlisted"
+    }
+  }
+}
+```
+

+### Error: "Unknown JWT iss (issuer)" - Status 401
+
+**Error completo:**
+```
+WebExtError: Received bad response from the server while requesting 
+https://addons.mozilla.org/api/v4/addons/...
+status: 401
+response: {"detail":"Unknown JWT iss (issuer)."}
+```
+
+**Causa**: Las credenciales AMO son inválidas o son credenciales de ejemplo/prueba.
+
+**Soluciones**:
+
+1. **Verificar que tienes credenciales reales de AMO:**
+   ```bash
+   cat private-keys/firefox-amo-credentials.json
+   ```
+   
+   Si ves valores como:
+   - `"apiKey": "user:12345678:123"` ← ❌ Ejemplo, no funciona
+   - `"apiSecret": "1234567890abcdef..."` ← ❌ Ejemplo, no funciona
+   
+   **Debes obtener credenciales reales:**
+
+2. **Obtener credenciales reales de AMO:**
+   - Ve a: https://addons.mozilla.org/developers/addon/api/key/
+   - Inicia sesión con tu cuenta de Firefox
+   - Click en "Generate new credentials"
+   - Dale un nombre descriptivo (ej: "ca-archive signing")
+   - **Copia el JWT issuer** → Este es tu `apiKey`
+   - **Copia el JWT secret** → Este es tu `apiSecret`
+
+3. **Actualizar archivo de credenciales:**
+   ```json
+   {
+     "web-ext": {
+       "sign": {
+         "apiKey": "user:TU_USER_ID_REAL:TU_KEY_ID_REAL",
+         "apiSecret": "tu_secret_real_de_64_caracteres_hexadecimales_aqui",
+         "channel": "unlisted"
+       }
+     }
+   }
+   ```
+
+4. **Volver a intentar:**
+   ```bash
+   ./build.sh --sign
+   ```
+
+**⚠️ Nota importante:**
+- El archivo de ejemplo tiene credenciales de prueba que NO funcionan
+- DEBES generar tus propias credenciales en AMO
+- Las credenciales son secretas, no las compartas ni las subas a Git
+- El archivo `private-keys/` está excluido de Git por seguridad
+
+### Error: "API Key invalid"
+
+**Causa**: Credenciales de AMO incorrectas o mal formateadas
+
+**Solución**:
+1. Verifica que copiaste correctamente API Key y Secret (sin espacios extra)
+2. Verifica formato JSON válido: `python3 -m json.tool private-keys/firefox-amo-credentials.json`
+3. Regenera credenciales en AMO si lleva mucho tiempo creadas
+4. Verifica que tu cuenta AMO tenga permisos de API habilitados
+
+### Error: "Private key not found"
+
+**Causa**: No se generaron las claves
+
+**Solución**:
+```bash
+./scripts/generate-keys.sh
+```
+
+### Error: "web-ext: command not found"
+
+**Solución**:
+```bash
+# Instalar dependencias locales
+npm install
+
+# El script usará automáticamente web-ext desde node_modules
+./build.sh --sign
+```
+
+**Alternativa (instalación global)**:
+```bash
+npm install -g web-ext
+```
+
+### Chrome: "Package is invalid: CRX_HEADER_INVALID"
+
+**Causa**: Archivo .crx mal formado
+
+**Solución**:
+- Usa la versión .zip para Chrome Web Store
+- Regenera el .crx con: `./build.sh --sign-chrome`
+
+### Firefox: Validación falla
+
+**Solución**:
+```bash
+# Validar primero sin firmar
+npm run lint
+
+# Corregir errores y luego firmar
+./build.sh --sign-firefox
+```
+
+## 📊 Automatización (CI/CD)

+
+## ⚠️ Problemas Actuales
+
+### 1. Firefox: No instala sin firma (RESUELTO EN DOCUMENTACIÓN)
+
+**Problema:**
+- Firefox Release NO permite deshabilitar `xpinstall.signatures.required`
+- Incluso con el flag en `false`, sigue requiriendo firma
+
+**Soluciones documentadas:**
+- ✅ **Opción 1 (Recomendada):** Firefox Developer Edition o Nightly
+  - Descargar: https://www.mozilla.org/firefox/developer/
+  - Permite `xpinstall.signatures.required=false`
+  - Instalación permanente sin necesidad de AMO
+
+- ✅ **Opción 2:** Carga temporal
+  - `about:debugging` → "Cargar complemento temporal"
+  - Se borra al cerrar Firefox, pero funciona inmediatamente
+
+- ✅ **Opción 3:** Firma con AMO (para distribución)
+  - Requiere credenciales reales de AMO (ver siguiente sección)
+  - `./build.sh --sign` genera `.xpi` firmado
+
+**Documentación:** [TROUBLESHOOTING.md#firefox](TROUBLESHOOTING.md#firefox-add-on-could-not-be-installed-because-it-is-not-signed-sin-poder-deshabilitar-firma)
+
+---
+
+### 2. Firma AMO: Requiere credenciales reales (PENDIENTE USUARIO)
+
+**Estado actual:**
+- ❌ Archivo `private-keys/firefox-amo-credentials.json` tiene credenciales de ejemplo
+- ❌ Error al firmar: "Unknown JWT iss (issuer)" - Status 401
+
+**Motivo:**
+Las credenciales de ejemplo NO funcionan. Valores actuales:
+```json
+{
+  "apiKey": "user:12345678:123",        ← ❌ Ejemplo, no válido
+  "apiSecret": "1234567890abcdef...",   ← ❌ Ejemplo, no válido
+}
+```
+
+**Acción requerida:**
+1. Obtener credenciales reales de AMO:
+   - https://addons.mozilla.org/developers/addon/api/key/
+   - Generar nuevo par de credenciales
+   - Copiar "JWT issuer" (apiKey) y "JWT secret" (apiSecret)
+
+2. Actualizar archivo:
+   ```bash
+   nano private-keys/firefox-amo-credentials.json
+   ```
+   Reemplazar con tus credenciales reales
+
+3. Volver a firmar:
+   ```bash
+   ./build.sh --sign
+   ```
+
+**Documentación:** [SIGNING.md#firefox](SIGNING.md#-paso-2-configurar-credenciales-de-firefox-amo)
+
+---
+
+### 3. Chrome: Manifest v2 bloqueado (RESUELTO EN DOCUMENTACIÓN)
+
+**Problema:**
+- Chrome 127+ (junio 2024) bloqueó Manifest v2
+- Esta extensión usa Manifest v2 (necesario para sql.js con `'unsafe-eval'`)
+- Error: "Manifest version 2 is deprecated/not supported"
+
+**Estado de navegadores (2026):**
+| Navegador | Estado | Solución |
+|-----------|--------|----------|
+| Chrome 127+ | ❌ Bloqueado | Usa Firefox, Edge o Brave |
+| Edge | ✅ Funciona | Modo desarrollador |
+| Brave | ✅ Funciona | Modo desarrollador |
+| Firefox | ✅ Completo | Soporte Manifest v2 indefinido |
+
+**Migración a Manifest v3:**
+- ❌ No implementada (requiere reescritura significativa)
+- ⚠️ Incompatibilidad: sql.js requiere `'unsafe-eval'` (prohibido en v3)
+- 💡 Solución futura: Migrar a IndexedDB nativa en lugar de sql.js
+
+**Documentación:** [TROUBLESHOOTING.md#chrome](TROUBLESHOOTING.md#chrome-manifest-version-2-is-deprecated-o-not-supported)
+
+---
+
+## 🎯 Recomendaciones de Instalación
+
+### Para Usuarios Finales
+
+**Mejor opción:** Firefox Developer Edition
+```bash
+1. Descargar: https://www.mozilla.org/firefox/developer/
+2. about:config → xpinstall.signatures.required → false
+3. ./build.sh
+4. Arrastra dist/ca-archive-3.0.0.xpi a Firefox
+```
+✅ Instalación permanente sin necesidad de firma
+
+**Alternativa rápida:** Carga temporal en Firefox
+```bash
+1. about:debugging#/runtime/this-firefox
+2. "Cargar complemento temporal"
+3. Selecciona manifest.json
+```
+⚠️ Se desinstala al cerrar Firefox
+
+**Para Chrome:** No compatible (usa Firefox, Edge o Brave)
+
+---
+
+### Para Desarrolladores
+
+**Testing local:**
+```bash
+# Carga temporal en Firefox
+about:debugging → manifest.json
+
+# O modo desarrollador en Edge/Brave
+edge://extensions/ → "Cargar extensión sin empaquetar"
+```
+
+**Construcción:**
+```bash
+# Empaquetar sin firma
+./build.sh
+
+# Empaquetar con firma (requiere credenciales AMO reales)
+./build.sh --sign
+```
+
+**Validación:**
+```bash
+# Lint con web-ext
+npm run lint
+
+# Verificar sintaxis manifest
+python3 -m json.tool manifest.json
+```

+### Firefox: "Add-on could not be installed because it is not signed" (sin poder deshabilitar firma)
+
+**Problema:** Firefox Release NO permite deshabilitar la verificación de firma desde Firefox 48+.
+
+**Causa:** 
+- `xpinstall.signatures.required=false` NO funciona en Firefox Release
+- Solo funciona en versiones Developer/Nightly/ESR Unbranded
+
+**Soluciones:**
+
+1. **Usar Firefox Developer Edition (RECOMENDADO):**
+   ```bash
+   # Descargar desde:
+   # https://www.mozilla.org/firefox/developer/
+   
+   # Luego en about:config:
+   xpinstall.signatures.required = false
+   ```
+
+2. **Usar Firefox Nightly:**
+   ```bash
+   # Descargar desde:
+   # https://www.mozilla.org/firefox/nightly/
+   
+   # Luego en about:config:
+   xpinstall.signatures.required = false
+   ```
+
+3. **Firmar en Mozilla AMO (para distribución):**
+   ```bash
+   # 1. Obtener credenciales:
+   # https://addons.mozilla.org/developers/addon/api/key/
+   
+   # 2. Configurar en:
+   # private-keys/firefox-amo-credentials.json
+   
+   # 3. Firmar:
+   ./build.sh --sign
+   ```
+
+4. **Carga temporal (limpia al cerrar Firefox):**
+   - `about:debugging#/runtime/this-firefox`
+   - Click "Cargar complemento temporal"
+   - Seleccionar `manifest.json`
+   - ⚠️ Se desinstala al cerrar Firefox
+
+### Chrome: "Manifest version 2 is deprecated" o "not supported"
+
+**Problema:** Chrome está deprecando/bloqueando Manifest v2.
+
+**Estado actual (febrero 2026):**
+- Chrome 127+ (junio 2024): v2 deshabilitado para nuevas extensiones
+- Chrome 136+ (2025): v2 puede estar completamente bloqueado
+- Edge/Brave: Soporte extendido hasta 2025-2026
+
+**Soluciones:**
+
+1. **Verificar versión de Chrome:**
+   ```
+   chrome://settings/help
+   ```
+
+2. **Si Chrome < 127 (solo advertencia):**
+   - ✅ La extensión funciona normalmente
+   - Ignora la advertencia de deprecación
+   - Instala en modo desarrollador normalmente
+
+3. **Si Chrome >= 127 (error de bloqueo):**
+   
+   **Opción A: Usar navegador compatible (RECOMENDADO)**
+   - Microsoft Edge: `edge://extensions/`
+   - Brave: `brave://extensions/`
+   - Ambos soportan Manifest v2 hasta ~2025-2026
+   
+   **Opción B: Usar Firefox**
+   - Firefox soporta Manifest v2 indefinidamente
+   - Mejor compatibilidad con esta extensión
+   
+   **Opción C: Esperar Manifest v3 (no disponible aún)**
+   - Estado: No implementado en esta extensión
+   - Requiere reescritura significativa:
+     - Service workers en lugar de background scripts
+     - Eliminar `webRequestBlocking`
+     - Eliminar `'unsafe-eval'` (conflicto con sql.js)
+   - Timeline: TBD
+
+4. **Workaround temporal (solo Chrome <140):**
+   
+   Algunos flags experimentales pueden ayudar:
+   ```
+   chrome://flags/#enable-mv2-extension-deprecation-warnings
+   ```
+   Cambiar a "Disabled" (solo retrasa advertencias, no evita bloqueo)
+
+**⚠️ IMPORTANTE:** 
+- Manifest v3 tiene limitaciones que dificultan esta extensión
+- sql.js requiere `'unsafe-eval'` (prohibido en v3)
+- Posibles soluciones v3: migrar a IndexedDB en lugar de sql.js
+
+### Chrome: "Could not load manifest"
+
+**Error completo:** `"manifest_version" key must be 3...`
+
+**Causa:** Chrome 127+ bloqueando Manifest v2
+
+**Solución:** Ver sección anterior "Manifest version 2 is deprecated"

+# Base de Datos de Classic Add-ons Archive
+
+⚠️ **ARCHIVO FALTANTE: `ca-archive-19030501.sqlite`**
+
+Este directorio debe contener el archivo de base de datos SQLite con el catálogo completo de add-ons clásicos de Firefox.
+
+---
+
+## 📊 Archivo Requerido
+
+**Nombre:** `ca-archive-19030501.sqlite`  
+**Tamaño:** ~50 MB  
+**Contenido:** 93,598 versiones de 19,450 Firefox add-ons clásicos
+
+---
+
+## ⚠️ Por qué falta
+
+Este archivo es muy grande para incluirse en Git. Debes obtenerlo de una de estas fuentes:
+
+### Opción 1: Releases de GitHub (si están disponibles)
+
+```bash
+# Buscar en releases del repositorio original
+# https://github.com/JustOff/ca-archive/releases
+
+# Si hay un release con la DB:
+cd content/db/
+wget https://github.com/JustOff/ca-archive/releases/download/vX.X.X/ca-archive-19030501.sqlite
+```
+
+### Opción 2: Versión Legacy (v2.x)
+
+Si tienes instalada la versión antigua (v2.x) de la extensión en Firefox ≤56:
+
+1. Buscar el archivo en el perfil de Firefox:
+   ```bash
+   # En Linux:
+   find ~/.mozilla/firefox/*.default* -name "ca-archive*.sqlite" 2>/dev/null
+   
+   # En Windows:
+   # %APPDATA%\Mozilla\Firefox\Profiles\*.default*\
+   ```
+
+2. Copiar aquí:
+   ```bash
+   cp /ruta/encontrada/ca-archive-19030501.sqlite content/db/
+   ```
+
+### Opción 3: Construir desde fuentes públicas
+
+Según el README original, los datos provienen de:
+- **AMO** (addons.mozilla.org)
+- **Wayback Machine** (web.archive.org)
+- Otros directorios públicos
+
+Necesitarías scripts para extraer y compilar estos datos en una base SQLite.
+
+---
+
+## 🔍 Verificar integridad
+
+Una vez obtenido el archivo, verifica:
+
+```bash
+# Tamaño (debe ser ~50 MB)
+ls -lh ca-archive-19030501.sqlite
+
+# Integridad SQLite
+sqlite3 ca-archive-19030501.sqlite "PRAGMA integrity_check;"
+# Debe retornar: ok
+
+# Ver cantidad de add-ons
+sqlite3 ca-archive-19030501.sqlite "SELECT COUNT(*) FROM addons;"
+# Debe retornar: ~19450
+
+# Ver cantidad de versiones
+sqlite3 ca-archive-19030501.sqlite "SELECT COUNT(*) FROM versions;"
+# Debe retornar: ~93598
+```
+
+---
+
+## 📁 Estructura de la Base de Datos
+
+La base de datos SQLite debe contener al menos estas tablas:
+
+- `addons` - Información de cada add-on (nombre, autor, descripción)
+- `versions` - Versiones de cada add-on (número versión, fecha, compatibilidad)
+- `categories` - Categorías de add-ons
+- `developers` - Información de desarrolladores
+
+---
+
+## 🚀 Después de obtener la DB
+
+1. **Colocar el archivo aquí:**
+   ```
+   content/db/ca-archive-19030501.sqlite
+   ```
+
+2. **Verificar permisos:**
+   ```bash
+   chmod 644 content/db/ca-archive-19030501.sqlite
+   ```
+
+3. **Recargar extensión en Firefox:**
+   ```
+   about:debugging#/runtime/this-firefox
+   → Click en "Recargar" (ícono ↻)
+   ```
+
+4. **Verificar carga:**
+   - La extensión mostrará: "Loading database for the first time. Please wait..."
+   - Primera carga puede tardar 30-60 segundos (carga y guarda en storage)
+   - Siguientes cargas serán instantáneas (se lee del storage)
+
+---
+
+## 🆘 Contacto
+
+Si no puedes obtener el archivo de base de datos:
+
+- **GitHub Issues:** https://github.com/JustOff/ca-archive/issues
+- **Autor original:** JustOff
+- **Descripción:** Solicitar enlace de descarga para `ca-archive-19030501.sqlite`
+
+---
+
+## 📝 Nota para Desarrolladores
+
+Si vas a generar tu propia base de datos desde cero, el esquema SQL esperado debe ser compatible con las consultas en:
+
+- `content/list.js` - Listados de add-ons
+- `content/addon.js` - Detalles de add-on individual
+- `content/versions.js` - Versiones disponibles
+- `content/tcloud.js` - Tag cloud de categorías
+
+---
+
+**Estado actual:** ❌ Archivo faltante (la extensión NO funcionará sin este archivo)  
+**Acción requerida:** Obtener `ca-archive-19030501.sqlite` de releases o versión legacy

+# Scripts de Construcción y Firma
+
+Este directorio contiene scripts de utilidad para construir y firmar la extensión.
+
+## Scripts disponibles
+
+### `generate-keys.sh`
+
+Genera claves privadas para firma de extensiones.
+
+**Uso:**
+```bash
+./scripts/generate-keys.sh
+```
+
+**Genera:**
+- Clave privada RSA para Chrome (2048-bit)
+- Extension ID de Chrome
+- Plantilla de credenciales para Firefox AMO
+- Hash de verificación de claves
+
+**Ubicación de claves**: `private-keys/`
+
+⚠️ **Importante**: Las claves NO se suben al repositorio. Haz backup seguro.
+
+## Construcción y firma
+
+Para construir y firmar extensiones, usa el script principal en la raíz:
+
+```bash
+# Desde la raíz del proyecto
+./build.sh --sign           # Firmar ambos navegadores
+./build.sh --sign-firefox   # Solo Firefox
+./build.sh --sign-chrome    # Solo Chrome
+```
+
+## Más información
+
+Ver documentación completa en:
+- [SIGNING.md](../SIGNING.md) - Guía completa de firma
+- [INSTALL.md](../INSTALL.md) - Guía de instalación
+
+## Seguridad
+
+Todos los scripts de firma requieren claves privadas que:
+- Están excluidas del repositorio Git (.gitignore)
+- Deben tener permisos restrictivos (600)
+- NUNCA deben compartirse públicamente
+
+Para verificar que las claves están protegidas:
+```bash
+git status private-keys/  # Debe mostrar "ignored"
+ls -la ../private-keys/   # Permisos deben ser 700/600
+```

+
+## ⚠️ IMPORTANTE: Seguridad
+
+- **NUNCA** subas estas claves a repositorios públicos
+- **NUNCA** compartas estas claves con nadie
+- Haz backup de estas claves en un lugar seguro
+- Si pierdes las claves, perderás el ID de la extensión de Chrome
+
+## Archivos
+
+### Chrome
+- `chrome-extension.pem` - Clave privada RSA 2048-bit
+- `chrome-extension-id.txt` - ID de la extensión derivado de la clave
+- `chrome-key-hash.txt` - Hash SHA256 para verificación
+
+### Firefox
+- `firefox-amo-credentials.json` - Credenciales de API de AMO (addons.mozilla.org)
+
+## Uso
+
+Las claves se usan automáticamente por los scripts de build:
+```bash
+./build.sh --sign        # Firma ambas versiones
+./build.sh --sign-chrome # Solo Chrome
+./build.sh --sign-firefox # Solo Firefox
+```
+
+## Regenerar claves
+
+```bash
+cd scripts
+./generate-keys.sh
+```
+
+**Nota:** Regenerar la clave de Chrome cambiará el ID de la extensión.
+
+## Obtener credenciales de Firefox
+
+1. Inicia sesión en https://addons.mozilla.org
+2. Ve a: https://addons.mozilla.org/developers/addon/api/key/
+3. Genera credenciales JWT
+4. Copia API Key (issuer) y API Secret
+5. Actualiza `firefox-amo-credentials.json`
