Stealth Browser Assistant by Henri Z

Stealth Browser Assistant helps you manage private browser tabs quickly and discreetly on Chrome, Edge, and Firefox.

Define private tabs using your own keywords or domains. SBA checks tab titles and URLs locally, then lets you control all matching tabs at once.

Key features

• Mute — Instantly mute matching tabs.
• Hide — Move matching tabs into a minimized stash window and restore them later.
• Emergency Action — Mute and hide matching tabs with one customizable shortcut.
• Match Feedback — Identify matching tabs through optional visual indicators.
• Keyboard Shortcuts — Mute, hide, trigger Emergency Action, or clean private data without opening the extension.

Premium features

Premium adds unlimited keywords, emergency tab closing, media pause on mute, and private data cleanup. Cleanup can remove matching browsing history, download history, cookies, and site data. Optional Auto Cleanup can run after the last matching tab is closed.

Privacy by design

• Keywords and settings stay locally in your browser.
• No browsing activity, URLs, history, or page content is sent to our servers.
• No tracking, analytics, or advertising.
• License requests contain only your license key and a hashed device identifier.

The free version includes the core tab detection, mute, hide, Emergency Action, and match feedback features. Upgrade to Premium when you need advanced automation and cleanup tools.

Available for Google Chrome, Microsoft Edge, and Mozilla Firefox.
