[Mozilla Enterprise] Firefox ESR 60.6.0 x64 - Not Uninstalling Correctly?

Hello,

I manage the software (SCCM) for  my domain and regularly update Firefox ESR, usually seamless...

This is my uninstall script:

TASKKILL /F /IM       Firefox* /T

IF EXIST "%ProgramFiles%\Mozilla Firefox" (
                "%ProgramFiles%\Mozilla Firefox\uninstall\helper.exe" -ms
                "%WinDir%\System32\timeout.exe" /T 10 /NOBREAK
                RMDIR /S /Q "%ProgramFiles%\Mozilla Firefox"
                DEL %Public%\Desktop\*Firefox*.lnk
                RMDIR /S /Q "%ProgramData%\Microsoft\Windows\Start Menu\Programs\Mozilla Firefox"
                REG DELETE /F HKEY_LOCAL_MACHINE\SOFTWARE\Mozilla
                REG DELETE /F HKEY_LOCAL_MACHINE\SOFTWARE\MozillaPlugins
                REG DELETE /F HKEY_LOCAL_MACHINE\SOFTWARE\mozilla.org
                REG DELETE /F HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Mozilla
                REG DELETE /F HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\MozillaPlugins
)

IF EXIST "%ProgramFiles(x86)%\Mozilla Maintenance Service" (
                "%ProgramFiles(x86)%\Mozilla Maintenance Service\Uninstall.exe" /S
                "%WinDir%\System32\timeout.exe" /T 10 /NOBREAK
                RMDIR /S /Q "%ProgramFiles(x86)%\Mozilla Maintenance Service"
)

"%WinDir%\System32\timeout.exe" /T 10 /NOBREAK
EXIT /B

This usually works flawlessly, however it seems that with 60.6.0 the helper.exe is unresponsive to the uninstall command, I also tried the uninstall.exe with the same switches in the same folder, no cigar.

Has there been a reported issue with the uninstallation of the browser or is there a newer way to do this?

Simply put, I usually uninstall the software client and then apply the update, however it stays stuck forever with the firefox uninstall phase.
