Tab Snoozer von tab-snoozer

Click the icon. Pick a time. The tab disappears. Tab Snoozer treats your open tabs like alarms — set one for "in 30 minutes," "tomorrow morning," or "next week," and it vanishes until then. When time's up, the tab reopens in a new window or a background tab, exactly as you left it. No more bookmarking just to remember. No more "I'll leave this open and get to it." The tab knows when to come back.

Works with one-shot snoozes or recurring schedules. Every snooze is visible in the popup so you can cancel early or bump it further out.
