# Preconfigure Software

## Firefox

### GPOs

Firefox can be preconfigured with GPOs [GPO-Template](https://github.com/mozilla/policy-templates/tree/bec1a5bbbaf0e3936f439a139f661d96a6b51a51).

### Policies

Or by a single file which is stored in a `distribution/policies.json`,

  on Windows: `C:\Program Files\Mozilla Firefox\distribution`

  on Linux: `/usr/lib64/firefox/distribution/`

This policies.json can be created with a Firefox-Extension [enterprise-policy-generator](https://addons.mozilla.org/en-US/firefox/addon/enterprise-policy-generator/)

#

#  Install Firefox policies.json

#

$policy_file = ".\policies.json"

$firefox_folder = "C:\Program Files\Mozilla Firefox"

$DistributionDirectory = "$firefox_folder\distribution"

if ( Test-Path -Path $firefox_folder -PathType Container ) {

  if (-not (Test-Path -LiteralPath $DistributionDirectory )) {

      try {

          New-Item -Path $DistributionDirectory  -ItemType Directory -ErrorAction Stop | Out-Null #-Force

      }

      catch {

          Write-Error -Message "Unable to create directory '$DistributionDirectory '. Error was: $_" -ErrorAction Stop

      }

      #"Successfully created directory '$DistributionDirectory'."

  }

  #"'$DistributionDirectory' exists"

  Copy-Item $policy_file $DistributionDirectory -force
