Thunderbird 138 has been released, marking another significant update for this widely used open-source email client. This new version brings several valuable features and improvements for users on various platforms, including GNU/Linux, macOS, and Windows.
Among the most notable changes is the introduction of a default color override for High Contrast mode. Previously, Thunderbird required users to manually set the color override option, which was set to "Never" by default. Starting with version 138, the application will automatically apply colors specified by the content when using a High Contrast theme, enhancing accessibility for users who rely on these themes.
Additionally, Thunderbird 138 adds message disposition buttons for new email alerts and allows users to customize new email notifications through macOS Settings. These changes aim to streamline user interactions and notifications within the platform.
As part of the release, multiple bug fixes have been implemented to enhance functionality. These include resolving truncation issues with message previews in notifications, fixing link and text color problems when using the Dark Reader extension, and improving folder management options in offline mode. Thunderbird also addresses a crash situation related to enabling adaptive message filtering.
The update further enhances OpenPGP support, allowing users to update accepted keys that have been reimported with new identities. It also addresses an issue where dual-signed emails (PGP and S/MIME) weren’t displaying correctly, alongside resolving a range of other bugs as well as 11 security vulnerabilities, making the update crucial for maintaining user security.
