FRITZ!Box Auto Login by Andrea-V Corrado

Fritz!Box Auto Login

Firefox extension that automatically logs into a Fritz!Box router's web interface.

Add-on page
- https://addons.mozilla.org/en-GB/firefox/addon/fritz-box-auto-login/

Overview
- This extension detects the Fritz!Box login page and will click the login button when the username and password fields are already filled (for example by you or by a browser password manager). The extension does not supply or store credentials itself.

Features
- Auto-login behaviour: when username and password fields on the Fritz!Box login page are already populated, the extension will automatically click the login button.
- Options page to view hostnames and IP addresses that the extension matches against (options.html, options.js).
- Lightweight content script approach (content.js) that detects the login form and triggers the submit action; it does not fill credentials.

Installation
- Recommended: Install from the official Mozilla Add-ons page above.
- For development/testing locally:
- Open about:debugging in Firefox → "This Firefox" → "Load Temporary Add-on..." and select the manifest.json from this repository.
- Or use web-ext to run and test locally.

Usage
- Open your Fritz!Box web interface (typically http://fritz.box or its IP).
- The extension does not store or fill credentials. If username/password fields are already filled (manually or by your browser/OS password manager), the extension will click the login button automatically.
- To view the hostnames and IP addresses the extension will act on, open options.html (Options) from the add-ons page or via the extension toolbar menu. Manage or change saved credentials using your browser or OS password manager.

Files of interest
- manifest.json — extension manifest and permissions.
- content.js — logic that runs on the router login page to detect the filled form and click login.
- options.html, options.js — UI to view hostnames and IP address lists used by the extension.

Privacy & Security
- Credentials: this extension does NOT store or transmit your username/password. It only automates the login action when the page fields are already populated. Manage credentials with your browser or OS password manager for best security.
- Permissions note: the manifest currently declares the storage permission but this version does not use it to persist credentials.
- No external servers: the extension operates locally in the browser and does not send credentials to remote servers (unless you intentionally modify the code to do so).
- Review content.js and options.js to audit exactly what is read from the page and what is displayed in the options UI.

Development
- Clone or open this folder in your editor.
- Use Firefox about:debugging → Load Temporary Add-on for quick iteration.
- For automated development with web-ext:
- Install web-ext (nodejs required): npm install --global web-ext
- Run: web-ext run --source-dir .
