Security Fixes: A Major Focus

Security remains a top priority for Google, and Chrome 135 is no exception. This release patches 14 vulnerabilities, some of which were reported by external security researchers.

To minimize risks, detailed information about these vulnerabilities remains restricted until most users have updated their browsers. Google also applies security restrictions if a vulnerability affects third-party libraries that other projects rely on.

Notable Security Fixes

Google continues to enhance internal security through advanced tools like AddressSanitizer (ASan), MemorySanitizer (MSan), and Control Flow Integrity (CFI). These measures help identify and fix vulnerabilities before they become widespread threats.

Acknowledgments and Community Support

Google has expressed gratitude to security researchers who reported issues during the development cycle, helping to prevent vulnerabilities from reaching the stable release.

Users experiencing issues or looking to explore new features can switch between release channels or report bugs via Chrome’s official support platforms.

With Chrome 135 now widely available, users can enjoy a more secure, optimized browsing experience, while developers gain access to improved tools and APIs.

What Undercode Say:

The release of Chrome 135 highlights Google’s ongoing commitment to security, performance, and stability. While this update doesn’t introduce major UI changes, it brings critical security fixes and backend improvements that enhance the overall experience.

Security First: A Recurring Theme

Google has been consistently strengthening Chrome’s security over the years. The inclusion of 14 vulnerability fixes in this release underlines the importance of proactive security measures. Among these, high-severity issues like CVE-2025-3066 (use-after-free vulnerability in Navigations) pose significant risks if left unpatched.

Google’s strategy of delaying full disclosure of these vulnerabilities until most users have updated is a smart move to prevent potential exploitation.

Developer-Friendly Enhancements

Although the official changelog doesn’t specify all the new developer-facing features, it’s clear that this update improves compatibility and stability. As Google continues refining JavaScript engines, APIs, and rendering performance, developers should stay tuned for further updates from the Chromium team.

Should You Update? Absolutely!

Even if you don’t notice visible changes, updating to Chrome 135 is highly recommended. Security fixes alone make it worth the upgrade, especially in an era where cyber threats are evolving rapidly. Additionally, background performance improvements ensure a smoother and more efficient browsing experience.

What’s Next?

With Chrome 135 out, Google will soon shift focus to Chrome 136, likely bringing more feature upgrades and experimental tools. As competition with Edge, Firefox, and Safari heats up, we can expect further innovations in privacy controls, AI-driven enhancements, and web compatibility.

If you’re a developer, keeping an eye on Chrome’s beta and Canary channels might give you a glimpse of upcoming web technologies before they hit the stable release.

Fact Checker Results

  • Security Focus Confirmed – Chrome 135 does indeed prioritize security with 14 major fixes, addressing vulnerabilities across multiple components.
  • Gradual Rollout Strategy – The phased rollout approach ensures stability while minimizing risks for users.
  • No Major UI Overhauls – While backend improvements are significant, users shouldn’t expect visible interface changes in this update.
