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.

Librewolf Winupdater FAQ

How do scheduled automatic updates work?
Enable the scheduled task option in WinUpdater, which prompts for administrator permissions. The task runs 1 minute after login and every 4 hours while the user is logged in.
How does updating work for LibreWolf Portable?
The portable package already contains WinUpdater. It checks once per day when LibreWolf-Portable.exe runs. Rename it to e.g. LibreWolf-ManualUpdater.exe to check only manually.
Does WinUpdater update itself?
Yes, it updates itself automatically. To update it manually instead, set UpdateSelf to 0 in its .ini file.
