## Description

## Tab Sleep Timer Fix

Tab Sleep Timer Fix is an essential Chrome extension that addresses a critical bug in the original Tab Sleep Timer by Daniel de Haas. The original add-on stops working when timers are cancelled, causing inconvenience for users who rely on timers to manage their browser tabs. This fixed version restores stability and ensures that you can put any tab to sleep reliably.

With Tab Sleep Timer Fix, you can set a sleep timer on any browser tab to automatically close or mute it after the timer expires. This helps manage tab clutter and saves system resources without manual intervention.

Please note: This fix is temporary and maintained until the original author updates the extension. If the original Tab Sleep Timer gets fixed, this version will be discontinued.
