Can I modify Firefox config (pref.js) using Powershell
I tried to script a PS to make changes to the Pref.js file; however, the changes do not stick? Is this is expected or done by default is there a way that I can modify the file without going to which single system?
PS Script
$TopDir = "$env:APPDATA\Mozilla\Firefox\Profiles" $FileName = 'prefs.js'
$DefaultProfileDir = (Get-ChildItem -LiteralPath $TopDir -Directory). Where({
$_.FullName -match '\.default' }).FullName
$FullFileName = Join-Path -Path $DefaultProfileDir -ChildPath $FileName
$Data = foreach($line in Get-Content $FullFileName) {
if( ($line.IndexOf('network.automatic-ntlm-auth.trusted-uris')) -ne -1)
{
If ($line.IndexOf('*') -ne -1) {
$line = $line.replace( '*' , 'abc.com,.abcd.com,.abcde.com')
}
}
$line
}
$data | Set-Content $FullFileName -Force

No need to edit prefs.js as you can do this via a policy.

Also, while Firefox is open, any changes to prefs.js are likely to be ignored or overwritten. You would need to make changes while Firefox is not running if you wanted to do it this way.
