Mozilla's Firefox 138.0 introduces significant enhancements, focusing on user convenience, cohesive design, and improved privacy. This release underscores Mozilla's commitment to evolving Firefox in line with modern operating systems and user expectations.

Enhanced Profile Management

Firefox 138.0 introduces a robust profile management system, allowing users to create distinct profiles for various activities such as work, study, or personal browsing. Each profile maintains its own bookmarks, tabs, browsing history, and settings, ensuring a personalized and organized experience. Users can name profiles and customize them with avatars and color themes for easy recognition. This feature is particularly beneficial for those who share devices or prefer to compartmentalize different aspects of their online life. (mozilla.org)

Windows 11 Design Integration

Aligning with Microsoft's design evolution, Firefox 138.0 enhances its integration with Windows 11 aesthetics. The introduction of acrylic-style pop-up windows provides a refined, translucent look that complements the Windows 11 interface. This visual update offers a more cohesive and immersive browsing experience for users on the latest Windows platform. (mozilla.org)

The update includes various security fixes and improvements, addressing potential vulnerabilities to enhance user protection. Additionally, the autofill mechanism for addresses and credit card details has been refined to better handle dynamically changing forms, ensuring more reliable and secure data entry. (mozilla.org)

Address Bar Enhancements

For users in the United States, Firefox 138.0 introduces weather suggestions directly in the address bar. By typing a weather-related term or city name, users can view the current weather conditions directly in the address bar dropdown, streamlining access to timely information. (mozilla.org)

Developer Enhancements

Developers will appreciate the support for the import map integrity field, allowing for the verification of dynamically or statically imported modules. Additionally, the implementation of INLINECODE0 enables brand checks to determine whether an object is an instance of Error, and support for INLINECODE1 improves compatibility with other browsers.
