Focus Timer Offline 作成者: v5

Focus Timer Offline is a simple productivity timer that runs directly from the Firefox toolbar. It helps users organize focused work sessions without requiring an account or external service.

• Start a focus timer from the Firefox toolbar.
• Choose a 5-minute session.
• Choose a 15-minute session.
• Choose a 25-minute session.
• Start and pause the countdown.
• Reset the current timer.
• Preserve the remaining time when the popup is closed.
• Restore an active timer when the popup is opened again.
• Display a completion message when the timer reaches zero.
• Work without an Internet connection.

1. Click the Focus Timer Offline icon on the Firefox toolbar.
2. Select a 5, 15, or 25-minute session.
3. Click Start to begin the countdown.
4. Click Pause to temporarily stop the timer.
5. Click Reset to return to the selected session length.

The extension stores only the information required to restore the current timer, such as the selected duration, remaining time, and expected completion time.

Closing the popup does not automatically cancel an active timer. When the popup is opened again, the extension calculates and displays the correct remaining time.


Focus Timer Offline does not collect, track, transmit, sell, or share user data.

The extension does not record websites visited, work activity, browsing behavior, completed tasks, personal information, or account information.

Only basic timer settings are stored locally on the user's device so the current session can be restored.


The extension does not request access to websites and does not use content scripts, remote code, analytics services, advertising services, or external APIs.


All timer functions operate locally inside Firefox. No account, cloud service, or Internet connection is required.


Because the extension does not use a persistent background process, completion behavior may depend on Firefox remaining open. The latest timer status is calculated when the extension popup is opened.
