About Hush Tabs – Sleep Inactive Tabs - Auto Tab Discard
Hush Tabs puts the tabs you're not looking at to sleep, so Chrome stays fast and light.
Open a tab and focus. After a delay you choose, your other tabs quietly fall asleep and free up memory. Click one and it wakes up right where you left it.
HOW IT WORKS
- Switch to a tab: the others start a countdown, shown live in the popup.
- When the countdown ends, they fall asleep and get a 💤 in their title, so you can spot them at a glance.
- Come back before the end and the tab simply stays awake.
IN YOUR CONTROL
- Choose a delay from instant to 1 hour, or switch to Manual mode and pick what sleeps yourself.
- Sleep a single tab, a whole window, or everything else with one click.
- Wake one tab or all of them just as fast.
- Keyboard shortcuts: Alt+Shift+H to turn on or off, Alt+Shift+J to sleep the other tabs.
PROTECTS WHAT MATTERS
- Exclude whole sites or specific pages from ever sleeping.
- Tabs that play audio, pinned tabs, tabs in a video call and pages with text you haven't sent yet stay awake.
SIMPLE AND PRIVATE
- A clean popup that lists your tabs and what each one is waiting for.
- No account, no ads, no tracking. Your settings stay on your device.
- Hush Tabs never reads the content of your pages.
