Firefox 135: Key New Features and Improvements
On February 4, 2025, Mozilla officially releases Firefox 135, a new version of the browser that brings several significant improvements for users and developers. Here are the most notable new features arriving with this update.
Improved Translation Feature
One of the most anticipated features is the expanded language support for the integrated translation function. Firefox 135 now allows users to translate web pages in simplified Chinese, Japanese, and Korean, in addition to offering Russian as a target language. This is a crucial step for users who rely on automatic translation to access content in languages other than their own.
Global Credit Card Autofill
Firefox 135 also makes strides in security and online shopping convenience. The credit card autofill feature, previously available only in select countries, is now globally expanded, providing a faster and more secure shopping experience for all users.
AI Chatbot and Security Enhancements
The AI Chatbot integrated in Firefox is also rolling out globally, offering an optional feature that users can activate through the sidebar or from Firefox Labs to choose their preferred AI provider. Additionally, in terms of security, Firefox 135 introduces certificate transparency, requiring web servers to provide clear proof of public disclosure of their certificates. This measure enhances trust in web connections.
New Protections and Navigation Enhancements
Firefox 135 introduces several additional protections against abuse of the history API. Websites will now be prevented from generating excessive entries in the browsing history, improving the experience when using back and forward navigation buttons. It also improves the behavior when closing tabs: on macOS and Linux, users can now close only the active tab when using the quit keyboard shortcut, without closing the entire window.
Improved New Tab Design
Regarding design, Firefox 135 extends the visual changes introduced in the previous version, including a new layout for the new tab page. The logo has been repositioned to prioritize web search, shortcuts, and recommended stories. Additionally, the design now supports up to four columns on large screens, improving accessibility and space usage.
Linux Optimization
Linux users will benefit from a new packaging of the binaries in XZ format, improving unpacking speed and reducing file sizes. Also, support for a post-quantum key exchange mechanism (mlkem768x25519) has been added, ensuring better security against future threats.
Web Developer Improvements
Firefox 135 brings several improvements that will be well received by developers. These include:
- Support for WebAuthn getClientCapabilities().
- Increased precision in PointerEvent coordinates.
- Improved WebExtension debugging, making it easier to work with content scripts and workers.
Global Update and Accessibility
Firefox 135 also introduces new settings for Android devices, such as the option to automatically submit crash reports to Mozilla to help fix issues. In addition, translations have been improved and several security vulnerabilities have been fixed, further enhancing the browser's reliability.
Conclusion
Firefox 135 comes with a blend of performance, security, and functionality improvements. Whether enhancing the browsing experience, offering better security, or facilitating AI interaction, this update further solidifies Firefox's position as one of the most comprehensive browsers on the market.
