About Librewolf Winupdater
LibreWolf WinUpdater checks for and installs LibreWolf updates on Windows for installed and portable instances. It can run manually, when the portable launcher starts, or on a scheduled task.
It stores the last check and update results in its INI file, updates itself automatically unless disabled, and waits until LibreWolf is closed if the browser is running. Full automatic installation requires administrator permissions, and scheduled checks run only while the user is logged in.
