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="'39.0-beta2'" --prerelease

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

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).
