About this extension
TabBrain helps you take control of your tabs when you have too many open and lose track of what you're doing.

HOW IT WORKS

TabBrain runs entirely in your browser — no external servers, no AI APIs, no data ever leaves your machine.

• Topic clustering — tabs are automatically grouped by content using text analysis
• Duplicate detection — auto-closes duplicate tabs before they pile up
• Stale tab cleanup — suspends tabs you haven't touched in days
• Snooze — hide a tab and have it come back later (1 hour, tomorrow, next week)
• Rescue list — accidentally closed tabs are saved and recoverable
• Container support — works with Firefox Multi-Account Containers
• Window grouping — view tabs organized by browser window
• Frequency learning — protects domains you visit often from being auto-closed
• Drag & drop — manually reorganize tabs between groups
• Export/Import — save and restore your tab groups as JSON
• Dark & light themes — follows your system preference or set manually

VIEWS

Click the TabBrain icon to see your tabs organized:
- By Topic — automatic content-based grouping
- By Window — grouped by browser window
- By Container — grouped by Firefox container (Personal, Work, etc.)

Search by tab title or URL to find any tab instantly.

SETTINGS

Customize stale thresholds, clustering sensitivity, excluded domains, notifications, and more from the settings page.

PRIVACY

TabBrain collects no data. Everything is stored locally in your browser using browser.storage.local. No analytics, no telemetry, no external requests.
