1. Ensure you are set for organizational deployment

Please see the organizational deployment guide

2. Get the package into your environment

  • Open Source or Commercial:
    • Proxy Repository - Create a proxy nuget repository on Nexus, Artifactory Pro, or a proxy Chocolatey repository on ProGet. Point your upstream to Packages cache on first access automatically. Make sure your choco clients are using your proxy repository as a source and NOT the default community repository. See source command for more information.
    • You can also just download the package and push it to a repository Download

3. Copy Your Script

choco upgrade firefox-beta -y --source="'INTERNAL REPO URL'" --version="'42.0-beta5'" --prerelease [other options]

See options you can pass to upgrade.

See best practices for scripting.

Add this to a PowerShell script or use a Batch script with tools and in places where you are calling directly to Chocolatey. If you are integrating, keep in mind enhanced exit codes.

If you do use a PowerShell script, use the following to ensure bad exit codes are shown as failures:

choco upgrade firefox-beta -y --source="'INTERNAL REPO URL'" --version="'42.0-beta5'" --prerelease

Write-Verbose "Exit code was $exitCode"
$validExitCodes = @(0, 1605, 1614, 1641, 3010)
if ($validExitCodes -contains $exitCode) {
  Exit 0

Exit $exitCode

Firefox Beta builds are for Firefox enthusiasts to test what's destined to become the next stable release of Firefox.

After spending six weeks in Firefox Developer Edition, we take the features that are stable enough, and create a new version of Firefox Beta.

Firefox channels (development cycle)

Every 6 weeks, Firefox developers take the current stable features of each build and introduce them into the next stable channel for further development. The Developer Edition is a special build containing features never moved forward since they would be rarely used by the average user and needlessly consume resources.

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).
