It includes all enhancements from previous versions up to 140 and introduces notable features such as a vertical tabs layout, the ability to unload tabs from memory without closing them, easier custom search engine integration, tab grouping, and an improved Reader View.

It offers a straightforward message search, customizable views, and supports various protocols including IMAP, POP, and RSS feeds. The dynamic toolbar is a significant new feature, adapting to show relevant options based on user activity, while the graphical user interface has been redesigned for better navigation and aesthetics.
Thunderbird Eclipse ESR also supports numerous Mozilla Add-Ons, allowing further customization to meet specific user needs. Security is a top priority, featuring a junk mail filter, digital signing, message encryption, S/MIME support, and compatibility with common security devices used by organizations.
