Pros of uBlock

• More comprehensive blocking capabilities, including network filters and cosmetic filtering
• Highly customizable with advanced user settings and dynamic filtering
• Lower CPU and memory usage, resulting in better performance

Cons of uBlock

• Steeper learning curve for non-technical users
• Requires more manual configuration to achieve optimal results
• May break some websites if not properly configured

Code Comparison

Privacy Badger:

BadgerStorage.prototype = {
  getItem: function(key) {
    return this._storage.getItem(key);
  },
  setItem: function(key, value) {
    return this._storage.setItem(key, value);
  }
};

uBlock:

µBlock.saveLocalSettings = function() {
  var µb = this;
  return µb.saveLocalStorageItem('immediateHiddenSettings', µb.hiddenSettings);
};

Both projects use JavaScript for their core functionality, but uBlock's codebase is more complex and extensive, reflecting its broader feature set and customization options. Privacy Badger focuses on a simpler, more automated approach to tracking protection, while uBlock provides granular control over content blocking and filtering.

Pros of Ghostery

• More comprehensive tracking protection, including social media trackers
• User-friendly interface with detailed analytics and performance metrics
• Customizable blocking options and whitelist functionality

Cons of Ghostery

• Closed-source, which may raise privacy concerns for some users
• Has been criticized for its business model of selling anonymized user data
• May cause more website breakage due to aggressive blocking

Code Comparison

Privacy Badger (JavaScript):

badger.storage.getBadgerStorageObject("action_map").setItem(
  tracker_fqdn,
  {
    heuristicAction: "block",
    dnt: false,
    userAction: "",
    nextUpdateTime: nextUpdateTime
  }
);

Ghostery (JavaScript):

ghostery.trackerdb.add({
  name: 'Example Tracker',
  category: 'Advertising',
  pattern: /example\.com/,
  domains: ['example.com'],
});

Both extensions use JavaScript for their core functionality. Privacy Badger focuses on learning and blocking trackers dynamically, while Ghostery relies on a predefined database of trackers. Privacy Badger's approach is more privacy-focused and adaptable, while Ghostery offers more immediate and comprehensive blocking based on its extensive tracker database.

Pros of DuckDuckGo Privacy Extension

• Integrates seamlessly with DuckDuckGo search engine for enhanced privacy
• Offers a more comprehensive privacy solution, including tracker blocking and HTTPS upgrading
• Actively maintained with frequent updates and improvements

Cons of DuckDuckGo Privacy Extension

• Less transparent development process compared to Privacy Badger
• May have a slightly higher performance impact due to additional features
• Not as focused on learning and adapting to new trackers over time

Code Comparison

Privacy Badger (JavaScript):

badger.storage.getBadgerStorageObject("action_map").setItem(domain, {
    heuristicAction: "block",
    userAction: "",
    dnt: false,
    nextUpdateTime: 0
});

DuckDuckGo Privacy Extension (JavaScript):

const trackerBlockingWhitelist = settings.getSetting('trackerBlockingWhitelist') || {}
trackerBlockingWhitelist[domain] = true
settings.updateSetting('trackerBlockingWhitelist', trackerBlockingWhitelist)

Both extensions use JavaScript for their core functionality. Privacy Badger focuses on a heuristic approach to blocking trackers, while DuckDuckGo Privacy Extension relies more on predefined lists and user settings. The code snippets show how each extension handles domain-specific actions, with Privacy Badger using a more detailed storage object and DuckDuckGo using a simpler whitelist approach.

Pros of Brave Browser

• Full-featured web browser with built-in privacy and security features
• Includes ad-blocking, fingerprint protection, and HTTPS upgrades
• Offers a cryptocurrency-based rewards system for users

Cons of Brave Browser

• Larger codebase and more complex than a simple browser extension
• Requires users to switch their primary browser for full benefits
• Some controversy around its cryptocurrency and ad replacement features

Code Comparison

Privacy Badger (JavaScript):

badger.storage.getBadgerStorageObject("snitch_map")
  .getItemClones().forEach(function(domain, tracker) {
    // Handle tracking domains
});

Brave Browser (C++):

void BraveShieldsHandler::BlockTracker(
    const std::string& tracker_url,
    const std::string& first_party_url) {
  // Implement tracker blocking
}

Summary

Privacy Badger is a focused browser extension for privacy protection, while Brave Browser is a complete web browser with integrated privacy features. Privacy Badger offers a simpler, more targeted approach to tracking prevention, whereas Brave provides a comprehensive browsing experience with additional features like ad replacement and cryptocurrency rewards. The choice between them depends on whether users prefer a standalone extension or are willing to adopt a new browser for enhanced privacy.

Pros of Multi-Account Containers

• Allows users to separate browsing contexts within the same browser window
• Provides more granular control over cookie isolation and site-specific settings
• Integrates seamlessly with Firefox's built-in features

Cons of Multi-Account Containers

• Limited to Firefox browser only
• Requires manual setup and management of containers
• May not block trackers as effectively as dedicated privacy extensions

Code Comparison

Multi-Account Containers:

async function createContainer(name, color, icon) {
  return browser.contextualIdentities.create({
    name: name,
    color: color,
    icon: icon
  });
}

Privacy Badger:

function updateTrackerPrevalence() {
  var trackerDomains = getTrackerDomains();
  for (var domain in trackerDomains) {
    badger.updateTrackerPrevalence(domain, trackerDomains[domain]);
  }
}

The code snippets highlight the different focus areas of each project. Multi-Account Containers deals with creating and managing container contexts, while Privacy Badger focuses on tracking and managing tracker domains for enhanced privacy protection.

Pros of AdguardBrowserExtension

• More comprehensive ad-blocking and content filtering capabilities
• Customizable filtering rules and whitelisting options
• Regular updates and active development

Cons of AdguardBrowserExtension

• Closed-source components may raise privacy concerns
• More complex user interface, potentially overwhelming for some users
• Resource-intensive due to extensive features

Code Comparison

PrivacyBadger (JavaScript):

badger.storage.getBadgerStorageObject("action_map").setItem(domain, {
  heuristicAction: "allow",
  userAction: "",
  dnt: false,
  nextUpdateTime: 0
});

AdguardBrowserExtension (TypeScript):

export function isHttpRequest(url: string): boolean {
    return url && (url.indexOf('http://') === 0 || url.indexOf('https://') === 0);
}

PrivacyBadger focuses on tracking protection using a learning algorithm, while AdguardBrowserExtension offers broader content filtering capabilities. PrivacyBadger's code snippet demonstrates its domain-based action mapping, while AdguardBrowserExtension's code shows a utility function for URL validation. Both projects aim to enhance user privacy and browsing experience, but AdguardBrowserExtension provides more extensive features at the cost of increased complexity and potential privacy trade-offs due to closed-source components.
