GETTING STARTED
Stealth Browser Assistant matches tabs using the Keywords you choose. Once configured, you can Mute, Hide, or use the Panic Button without searching through your tab bar.
The setup at a glance
Start with the free features. You can add Premium capabilities later if you need deeper cleanup or Close matching tabs.
Add up to five Keywords for free.
Open a tab whose URL or title matches.
Use Mute, Hide, or the Panic Button.
GETTING STARTED
Follow each step with the matching product screenshot, then test the action in your own browser.
Select the Stealth Browser Assistant icon in your browser toolbar, then open Settings. Pinning the extension first makes the popup easier to reach.
Enter a domain or ordinary word in the Keywords field, then press Enter or select Add. SBA checks both the tab URL and title using case-insensitive substring matching.
Note: SBA does not decide what is private. Your own Keywords define which tabs match.
Open or refresh a page whose URL or title contains one of your Keywords. Match hit feedback can replace the tab icon, and the optional red border flash can make an active match easier to notice.
Open the SBA popup. Mute applies browser-native tab muting to current matches and keeps muting new matches while it is on. Hide moves matching tabs into a minimized temporary window and mutes them.
Note: Hide is not encryption or deletion. It moves matching tabs into a minimized temporary window until Hide is turned off.
In Settings, choose the Panic Button action. The free option turns on Mute and Hide together. Premium can instead Close matching tabs immediately.
Important: Close matching tabs is destructive. Recovery depends on your browser's own reopen-closed-tab behavior.
Use the shortcut management link in Settings to open your browser's extension-shortcut page. Assign combinations that do not conflict with your browser or operating system.
Premium can remove matching browsing history, Downloads history, and Cookies & site data. Each category is off by default and requests its browser permission only when you enable it.
Important: Review the selected data types before running cleanup. Clean private data cannot restore deleted browser records.
QUICK REFERENCE
Use the defaults immediately or replace them in your browser's extension shortcut settings.
On macOS, Alt is shown as Option. All shortcuts are customizable.
| Action | Default shortcut |
|---|---|
| Mute | Alt + Shift + M |
| Hide | Alt + Shift + H |
| Panic Button | Alt + Shift + E |
| Clean private data | Alt + Shift + C |
TROUBLESHOOTING
Check whether the tab URL or title actually contains one of your Keywords. Matching is a case-insensitive substring match, not a regular expression.
Open your browser's extension shortcut settings and confirm that the shortcut is assigned and does not conflict with another command.
Open the SBA popup and turn Hide off. SBA will restore recorded tabs to the original window when possible, or to the most recently focused window.
Browser internal pages, extension-store pages, and some protected pages block script injection. Browser-native Mute may still work even when page-level feedback or Pause media cannot run.
PRIVACY BY DESIGN
Keyword matching happens locally. SBA does not send your Keywords, tab URLs, page content, or browsing history to its License service. Network requests are limited to License Key activation and status checks.
