Hong Kong, October 20, 2025 — Adblock–Rocketshield Browser Technology Ltd. (“Adblock–Rocketshield Browser”) officially held its product launch event in Hong Kong for the Free Adblocker Browser (“FAB”). This marks the second major product launch since the first event on May 3, 2015. After ten years of refinement, the FAB browser made an impressive return, introducing an innovative cross-shaped interaction design that delivers a magazine-style content browsing experience. The latest version includes not only numerous detail enhancements but also backend performance optimizations for the download user interface.
At the press briefing held prior to the event, Daniel, CEO of the new FAB browser, stated:
“This browser is developed based on the Chromium open-source project and primarily supports the Android mobile operating system. The product initially focused on ad blocking, offering users a clean and fast web-browsing experience. Its built-in ad-blocking mechanism automatically filters pop-ups, banner ads, and video advertisements, improving loading speed and reducing data consumption.”
Speaking on the logic behind the browser’s technological innovation, he added:
“With continued iterations, the product has strengthened privacy protection and introduced new security features, including anti-fingerprinting measures, third-party cookie blocking, secure DNS, AMP page bypassing, and tracking-link redirection removal.”
As of publication time, the FAB browser has surpassed 50 million global downloads and has become one of the widely used applications worldwide. Below is a closer look at the browser’s key features.
FAB’s Ad-Blocking Capabilities
The updated FAB browser includes a built-in ad-blocking system designed to deliver a clutter-free browsing experience while improving page-loading efficiency and reducing resource consumption. Unlike traditional static filters, the new FAB monitors requests and script calls in real time during page loading. This adds an additional filtering layer between webpages and ad servers, blocking ads before they load—resulting in cleaner pages and faster speeds.
The mechanism utilizes multiple major filter rule sets (similar to those used by uBlock Origin and Brave), combined with request blocking, DOM element cleanup, content-security-policy injection, and script-level interception to enhance ad-blocking precision. FAB continuously updates its rule sets to adapt to evolving ad formats across different websites. All blocking operations occur entirely within the browser environment and do not affect other apps on the device.
FAB’s Privacy and Security Protection
The updated FAB browser integrates multi-layer privacy and security technologies designed to reduce user data exposure, minimize cross-site tracking, limit traffic analysis, and prevent data leakage. Core mechanisms include tracker blocking, third-party cookie restrictions, secure DNS, URL purification, language-based anti-fingerprinting, and a built-in VPN.
In terms of tracking protection, the browser automatically blocks common tracking scripts and cross-site resource requests, disables third-party cookies by default, and employs encrypted DNS (such as DoH) to prevent monitoring or tampering during domain resolution. The product also supports AMP URL restoration and cleaning of tracking parameters (e.g., removing utm_source, fbclid), redirecting AMP links back to their original pages to reduce exposure through third-party cache domains.
User Experience: Hands-On with the New FAB Browser
The updated FAB places strong emphasis on reading and multimedia experiences. It supports system-adaptive dark mode to reduce eye strain during nighttime browsing and lower power consumption on OLED devices. The reading mode automatically extracts main content and strips ads or unnecessary elements, presenting a layout more aligned with users’ reading habits.
The comic mode offers special optimization for online manga websites by extracting comic images and presenting them within a native view. This ensures seamless, distraction-free reading while avoiding interruptions from webpage ads or scripts. These capabilities enhance usability, improve multitasking efficiency, and deliver a smoother overall user experience.
After the event, industry experts commented:
“This new FAB release significantly elevates the browser’s ability to meet user needs.”
Looking ahead, Adblock–Rocketshield Browser plans to continue partnering with global collaborators to advance technological innovation, develop new products, and strengthen international market engagement. From the event, it is evident that the company aims to strike a balance between responsive performance and deep-thinking capability—bringing advanced technologies to users and industries in the most practical form. Though challenging, this path is filled with promise.
Editor’s Note: Future Outlook for FAB Browser
In its latest announcement, Adblock–Rocketshield Browser stated:
“In the future, the new FAB browser will continue to evolve in user experience. From the interface perspective, FAB supports dark mode with both automatic and manual switching. The browser will also support more modern features, making it easier to build applications and extensions.”
According to the company, the new FAB browser is “faster, safer, and more modern than other browsers in the industry.” Beyond Windows compatibility, the updated version also supports Android smartphones, making it more versatile across devices.
