• Session Management: Supports restoring the previous session, including tabs and their state, enhancing usability without compromising security.

Darkelf Browser incorporates robust adblocking functionality to enhance privacy and browsing experience:

1. Domain Blocking: The AdblockUrlRequestInterceptor class blocks requests to specific domains listed in the blocked_domains parameter, preventing unwanted content from loading.

2. Rule-Based Filtering: Custom rules in the AdblockUrlRequestInterceptor class enable filtering based on content type. This includes blocking CSP reports, large media files, and other specified types of requests.

3. Adblock Pattern Management: The load_adblock_list function aggregates adblock patterns from multiple sources, including popular ad-blocking lists and custom rules for sites like YouTube. Patterns are processed using the BeautifulSoup library to handle HTML content effectively.

4. Tracking Protection: The TrackerInterceptor class prevents requests to known tracking domains. Tracking domains are sourced from JSON files and processed with the json module, ensuring comprehensive tracking protection.

• Canvas Fingerprinting Protection: Modifies or blocks the ability of websites to read canvas data. This prevents websites from creating a unique fingerprint based on the rendering of graphics on the user's device.

• User-Agent Spoofing: Randomizes or standardizes the user-agent string sent to websites, making it difficult to identify the browser and operating system version.

• WebGL Fingerprinting Protection: Alters or blocks WebGL information to prevent fingerprinting based on the graphics hardware and driver details.

• Font Fingerprinting Protection: Limits the list of available system fonts exposed to websites, preventing fingerprinting based on the unique set of installed fonts.

• Media Device Enumeration Blocking: Prevents websites from accessing detailed information about the user's media devices (e.g., cameras, microphones), which can be used for fingerprinting.

• Timezone Spoofing: Changes or hides the timezone information to prevent websites from determining the user's geographical location based on their timezone.

• Language and Locale Spoofing: Randomizes or standardizes language and locale settings to prevent fingerprinting based on these attributes.

• Screen Resolution and Color Depth Spoofing: Modifies or hides screen resolution and color depth information to prevent websites from creating a unique fingerprint based on the display properties of the device.

• Hardware Concurrency Spoofing: Changes the reported number of logical processors (CPU cores) to prevent fingerprinting based on the hardware concurrency.

• Audio Fingerprinting Protection: Alters or blocks audio context information to prevent fingerprinting based on the audio hardware and capabilities.

• Battery Status API Blocking: Blocks access to the Battery Status API, preventing websites from tracking battery levels and charging status, which can be used for fingerprinting.

• Network Information API Blocking: Blocks access to the Network Information API, preventing websites from accessing network type and speed information, which can be used for fingerprinting.

• ETag and Cache-Control Manipulation: Modifies or disables ETag headers and cache-control mechanisms to prevent tracking via caching techniques.

• JavaScript Hooks: The browser employs JavaScript hooks to intercept and modify calls to functions and APIs that can be used for fingerprinting, such as navigator, screen, document, and window properties.

• Built-In: Built-in features to spoof or block fingerprintable attributes dynamically, providing an extra layer of protection.

• Configuration Options: Provides user-configurable options to enable or disable specific anti-fingerprinting techniques, allowing users to balance privacy and functionality according to their needs.

These techniques collectively reduce the uniqueness of the user's browser environment, making it harder for websites to track users based on their browser and device characteristics.
