Auto Shutdown (WebExtension)

Shutdown, hibernate, restart, suspend, or run a custom command when all downloads are finished

The Auto Shutdown (WebExtension) lets you automate system commands after all downloads finish in your browser. It supports shutting down, hibernating, restarting, suspending, or running any custom OS-level command such as launching applications or playing music.

To enable these features, a native messaging application must be installed on your computer. This extension is perfect for users who want to save power or run specific tasks automatically after downloads end. For installation and support details, visit the official page or report issues on GitHub.

User reviews

User reviews indicate that Auto Shutdown (WebExtension) can work well on some Windows 10 machines, providing useful automatic shutdown or restart features with countdown timers. However, many users experience failures where the intended actions do not execute, complicated installation requirements involving native clients confuse users, and error messages are unclear with no straightforward fixes. Documentation is insufficient and often Chrome-centric, leading to frustration. Despite these issues, some appreciate the add-on and the author's responsiveness on GitHub.
Pros
  • Works flawlessly on Windows 10 for some users.
  • Useful for scheduling automatic shutdown or restart actions.
  • Author is responsive on GitHub issues.
  • Provides countdown timer functionality for shutdown actions.
Cons
  • Does not work reliably on many systems, especially Windows 7 and some Windows 10 versions.
  • Requires complicated setup including installing additional native clients or software.
  • Error messages about incorrect paths with no clear way to fix them via options.
  • Documentation and tutorials are unclear and often focused on Chrome rather than Firefox.
