This extension does not collect, store, or transmit any personal data or browsing information to external servers. All proxy configurations are stored locally in your browser using the browser's built-in storage API. Proxy credentials (usernames and passwords) are stored locally and are only transmitted to the proxy servers you configure. No telemetry, analytics, or tracking is implemented in this extension.

Примечания для проверяющих:
This extension is built with vanilla JavaScript and does not require any build process. The source code is unminified and ready to review. All files are included in the submission package.

The extension uses the following Firefox APIs:
- proxy: for managing proxy configurations
- storage: for saving user configurations locally
- webRequest/webRequestBlocking: for applying proxy settings to network requests

No external libraries or frameworks are used. The extension works entirely client-side with no external server communication.

Test credentials are not required as the extension manages user-provided proxy servers.
