Firefox extension inventory

Avatar
Lord, Jerry
Updated

Sample PowerShell code for getting the Firefox extensions and putting in WMI for collection with PDQ inventory. I did this after the Chrome extension inventory to see if it could be done as easily. As with any environment your mileage may vary.

Updated to fix user profile scanning error.

May need to remove the Permissions field if inventorying with SCCM.

# PS script to get FireFox Ext and put in WMI
# Some script code from Ivanti. 
# Original idea I saw was from SKissinger for Chrome Ext for SCCM 2012. 

# Default extensions are ignored since they aren't visible to users. 

# Need to run with admin permissions to manipulate WMI.


function Convert-UTCtoLocal {
param(
[parameter(Mandatory=$true)]
[String] $UTCTime
)

    $strCurrentTimeZone = (Get-WmiObject win32_timezone).StandardName
    $TZ = [System.TimeZoneInfo]::FindSystemTimeZoneById($strCurrentTimeZone)
    $LocalTime = [System.TimeZoneInfo]::ConvertTimeFromUtc($UTCTime, $TZ)
    return $LocalTime
}



#setup or clear WMI class
if(Get-WmiObject -List | where { $_.Name -eq "pdqFireFoxExtension"}){

    #Clear existing WMI entries to re-enumerate extensions
    #Get-WmiObject pdqFireFoxExtension | Remove-WmiObject
    Remove-CimInstance -Query 'select * from pdqFireFoxExtension'
