How to Download Thunderbird 143
Users can download Thunderbird for Linux, Windows, and macOS directly from the official website. It is recommended to download the monthly release build, now at version 143. For those preferring stability, the Extended Support Release (ESR) is a suitable alternative.
For users on the monthly release builds, in-app updates are available by navigating to the Help menu and selecting About. Linux users can update through their package managers using DEB, Flatpak, or Snap builds.
If using Thunderbird ESR, note that feature updates and critical fixes are applied on a separate schedule from the monthly releases.
