Close & Forget Tab (Stealth Edition)

A lightweight Chrome/Firefox extension that lets you close a tab and instantly forget it — clearing 1 minute of history — as if it was never opened.

We named it Utility Kit by default to make the extension look stealthy and generic.

Features

• Close & Forget: One click wipes a tab’s browsing data after closing.
• Stealth Mode: Shows up as Utility Kit in the extension list.
• Custom Labeling: Inside the popup, users can rename the extension title and buttons to fit their cover story.
• Keyboard Shortcuts: Assign a hotkey to instantly close & forget a tab.
