Falcon Browser

To customize Falkon Browser (formerly known as QupZilla) for maximum online safety, you must manually adjust several default options, as its most rigid security features are turned off out of the box. Built on the Chromium-based QtWebEngine, Falkon is highly lightweight but requires active optimization to shield your data.

Note: If you are looking for enterprise security involving the CrowdStrike Falcon Browser Extension or Falcon Secure Access, management is handled strictly through centralized IT policies via the ⁠CrowdStrike Falcon Console rather than local user settings. 🛡️ Turn On Advanced Security Protections

Navigate to Edit ➔ Settings ➔ Browsing to adjust core code execution rules:

Enable XSS Auditing: Check the box for XSS Auditing. This active defense mechanism stops Cross-Site Scripting attacks from executing malicious scripts within your active session.

Restrict JavaScript Permissions: Limit or block universal JavaScript permissions. Only allow JavaScript on websites you explicitly trust to reduce the risk of drive-by malware downloads. 🛑 Optimize Privacy and Ad-Blocking Filters

Falkon includes a built-in ad blocker that prevents malicious scripts from loading:

Activate EasyPrivacy: Go to the ad-block settings, add a new subscription, and select the EasyPrivacy preset. This stops web trackers and telemetry from profiling your machine.

Block Third-Party Cookies: Under privacy preferences, configure the browser to block all third-party tracking cookies by default to enforce containerized tracking limits. 🔒 Secure or Replace the Internal Password Manager

Avoid the Default Database: By default, Falkon’s internal password manager stores user data in an unencrypted plaintext database.

The Fix: Disable the built-in password saving feature completely. Use a dedicated, sandboxed external password manager application to manage your login credentials safely. 🧼 Enforce Absolute Data Sanitization

Limit data exposure by automating the removal of local footprints:

Automate Data Destruction: Configure the history and privacy settings to automatically clear cache, browsing history, and HTML5 local storage every time you close the browser window.

Spoof User Agents: Use Falkon’s built-in feature to change your User Agent string without installing third-party extensions. This masks your exact browser configuration and helps prevent browser fingerprinting. CrowdStrike.com Secure work and access in any browser – CrowdStrike.com
