CCleaner Browser: Privacy‑Focused, Lightweight Browsing for Windows

CCleaner Browser is a Windows-only web browser developed by Piriform that emphasizes built-in privacy, security, and resource efficiency. Intended for users who prefer integrated protections over multiple add‑ons, it bundles ad blocking, anti‑tracking, anti‑fingerprinting and several security safeguards alongside tools for cleaning browsing data and managing passwords.

Performance and Resource Management

The browser has been reworked to reduce memory and CPU usage. According to the developer, background tabs are automatically suspended based on available memory, which can lower resource consumption by up to 50%. Battery‑saving optimizations are also included, with claims of up to 20% extended laptop battery life when enabled. These behaviors are configurable via a Performance Manager in the settings.

Privacy and Anti‑Fingerprinting

Privacy features are central to the browser’s design. Anti‑Tracking blocks third‑party trackers, while Anti‑Fingerprinting (v2.2) attempts to mask browser attributes such as version, language and add‑ons to make cross‑site identification more difficult. A Stealth Mode prevents browsing history from being stored and clears tracking cookies and cache from that session.

Security Features

• Anti‑Phishing and Malware Blocking — blocks malicious sites and downloads to reduce exposure to threats.
• Webcam Guard — prevents applications and malware from accessing the webcam without consent.
• Extension Guard — restricts unwanted add‑ons while allowing trusted extensions to be installed.
• Forces HTTPS — upgrades connections where possible to encrypt traffic in transit.

Built‑in Utilities and Convenience

Integrated tools aim to replace common third‑party extensions: a native ad blocker reduces intrusive ads and page load, a Privacy Cleaner clears history, cache and cookies to free space and protect privacy, and a password manager stores and autofills login credentials. Ad‑block aggressiveness and tracker protection levels can be adjusted within the browser.

Practical Applications and Target Users

• Suitable for Windows 10 and 11 systems where integrated privacy and security controls are preferred over adding multiple extensions.
• Useful for users who want to reduce ads and tracking without managing separate tools or extensions.
• Offers options for conserving system resources and extending battery life on portable devices.

Installation and System Requirements

The browser is available for Windows 10 and 11. The vendor presents the installer as compact and straightforward: download and launch to begin using the browser with default protections enabled.
