Mozilla has announced the release of Mozilla Thunderbird Eclipse ESR 140.1.0, a powerful and free email application that excels in customization and user experience. The latest update is part of the extended support release (ESR) cycle, which began in June 2025, and promises to be supported for approximately one year. This version includes features and improvements derived from Firefox releases up to version 140.
Key enhancements in this release include a vertical tab layout, the ability to unload tabs from memory without closing them, easier addition of custom search engines, tab grouping, and an improved Reader View with more text and layout options. Additionally, the application now defaults to HTTPS in the address bar and incorporates enhanced privacy features such as HTTPS-First mode and Bounce Tracking Protection in Strict Enhanced Tracking Protection (ETP) mode.
Mozilla Thunderbird Eclipse ESR prioritizes speed, safety, and user-friendliness, making it suitable for both individual and organizational use. It offers built-in tools like a straightforward message search, customizable views, and support for various protocols including IMAP, POP, and RSS feeds. A notable feature of the latest release is a dynamic toolbar that adjusts to display frequently used options based on the active tab or workspace, complemented by a redesigned graphical user interface (GUI) for easier navigation.
The application continues to support a wide array of Mozilla Add-Ons, allowing users to further enhance its capabilities. Security is a significant focus, with features such as an effective junk mail filter, digital signing, message encryption, and compatibility with enterprise-grade security devices.
For users seeking mobility, a portable version of Mozilla Thunderbird Eclipse ESR is also available.
In summary, Mozilla Thunderbird Eclipse ESR 140.1.0 delivers not only a robust email management experience but also emphasizes customization and security, making it a dependable choice for users who prioritize efficiency and privacy in their communication. As the application evolves, it is likely to continue integrating more features and improvements that meet the changing needs of its user base
