Thunderbird is a free email application that’s easy to set up and customize – and it’s loaded with great features!

This package installs Thunderbird in the first language which matches this list:

  1. Install arguments override parameter if present, e.g. choco install Thunderbird -packageParameters "l=en-GB". To get a list of all available locales have a look at this folder:
  2. If Thunderbird is already installed: the same language as the already installed Thunderbird.
  3. The Windows system language where the Thunderbird package gets installed.
  4. If Thunderbird does not support the system language, it will fallback to “en-US”

To install Mozilla Thunderbird, run the following command from the command line or from PowerShell:

C:\> choco install thunderbird --version

To upgrade Mozilla Thunderbird, run the following command from the command line or from PowerShell:

C:\> choco upgrade thunderbird --version

Virus Scan Results

In cases where actual malware is found, the packages are subject to removal. Software sometimes has false positives. Moderators do not necessarily validate the safety of the underlying software, only that a package retrieves software from the official distribution point and/or validate embedded software against official distribution point (where distribution rights allow redistribution).

Chocolatey Pro provides runtime protection from possible malware.
