The Extension Manager adds, removes, disables, enables, and updates LibreOffice extensions.
For security reasons, the installation and removal of extensions are enabled and are controlled by settings in the Expert Configuration. To disable extensions installation or removal, search for the string ExtensionManager in the Expert Configuration search box and set properties DisableExtensionRemoval to true and/or DisableExtensionInstallation to true.
