Zen Browser has officially launched its new version, 1.18.2b, which brings a series of significant updates and enhancements aimed at improving user experience and security. This release not only focuses on critical security fixes but also introduces new features and optimizations.
One of the key highlights of this update is the resolution of security vulnerabilities. A moderate-severity issue in the Anti-Tracking component, identified as CVE-2026-24868 by researcher Masato Kinugawa, has been addressed. Furthermore, a high-severity use-after-free flaw in the Scrolling and Overflow section, reported by Hiroyuki Ikezoe under CVE-2026-24869, has also been fixed. These changes significantly enhance the browser's security posture, ensuring a safer browsing experience for users.
In addition to security improvements, Zen Browser 1.18.2b integrates an updated Gecko engine from Firefox version 147.0.2. This integration not only boosts performance but also enriches the browser's functionality, allowing users to enjoy a more seamless experience similar to that of Firefox.
The update also brings enhancements to tab management. Users can now take advantage of a new setting that allows them to close tabs adjacent to their most recently used tab, providing greater flexibility in organizing their workspace. Furthermore, numerous bug fixes enhance the overall stability and usability of the browser. Long-standing issues, such as unexpected blank windows appearing during tab manipulation and the occasional disappearance of browser features, have been resolved, contributing to a smoother user experience.
Another significant improvement addresses user feedback regarding pinned tabs at startup, which has now been rectified. Additionally, minor adjustments to window behavior and system integration, including improved data migration paths and syncing routines, ensure that the browser operates harmoniously within users' systems.
Overall, Zen Browser 1.18.2b represents a substantial upgrade that not only prioritizes security but also enhances usability with new features and optimizations. Users are encouraged to update to this latest version to take full advantage of these improvements.
