ResetKioskRedux автор David Caron

Resets the current tab to the browser home page after a configurable inactivity.

Options for preventing right-clicking, timeout in seconds, and whether to close other tabs or not are located in the extensions 'Options' in the Extension menu.

Minimum timeout is 30 seconds, default is 60 seconds.

Inspired by https://github.com/cuetus/resetkiosk, rewritten as a webextension for modern Firefox.
