Summary of Changes

Hello, I'm Gemini Code Assist¹! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request introduces a significant feature: an "Auto Mode" for browser fingerprint generation. This mode leverages Camoufox's built-in browserforge to automatically create unique and randomized browser fingerprints for each instance launch. By dynamically adjusting properties like user agent, screen dimensions, WebGL details, and available fonts/voices, this feature aims to enhance privacy and simplify the management of browser profiles, reducing the need for manual configuration.

Highlights

• Automatic Fingerprint Generation: Introduced an "Auto Mode" for fingerprint generation, allowing the application to automatically create unique browser fingerprints on each launch using Camoufox's built-in browserforge.
• New auto_fingerprint Module: Added a new Rust module (auto_fingerprint.rs) responsible for generating randomized browser properties such as navigator, screen, WebGL, fonts, and voices.
• Randomness Integration: Integrated the rand crate to facilitate the generation of random values for fingerprinting, ensuring diverse and unpredictable profiles.
• Fingerprint Data Files: Included fonts.json and voices.json data files to provide comprehensive lists of fonts and voices for different operating systems, used in the auto-fingerprinting process.
• Configuration and UI Updates: Updated the FingerprintConfig structure and the instance launch logic to support the new auto_fingerprint toggle, and implemented a new UI toggle in the instance settings modal to activate or deactivate this feature.

Code Review

The pull request introduces an automatic fingerprint generation toggle, enhancing the flexibility of instance configurations. The changes correctly integrate the new auto_fingerprint field into the FingerprintConfig and update the logic for generating CAMOU_CONFIG based on this setting. A new Rust module auto_fingerprint.rs and associated JSON data files (fonts.json, voices.json) have been added to support this feature. The Svelte component InstanceSettingsModal.svelte has been updated to include the UI for the auto-mode toggle and to conditionally display manual fingerprint settings.

One critical issue was identified in the auto_fingerprint.rs module related to a non-existent method call, which will prevent compilation. Additionally, some inline styles in the Svelte component could be refactored for better maintainability.

The is_none_or method is not a standard Rust method and will cause a compilation error. You likely intended to use map_or to provide a default value if the third part of the split string is missing, or to check if it matches "local" otherwise.

Suggested change

	"isLocalService": parts.get(2).is_none_or(|t| *t == "local")
	"isLocalService": parts.get(2).map_or(true, |&t| t == "local")

The inline styles for the auto-mode-panel and the button are quite verbose. Consider extracting these into dedicated CSS classes for better maintainability and readability. This would make the template cleaner and easier to manage style changes globally.
