Auto Close Tabs

What is Auto Close Tabs?

Auto Close Tabs completely removes inactive tabs from your browser, providing maximum memory savings and system performance improvement. Unlike suspension, closed tabs are permanently removed and must be restored from browser history or snapshots.

How Auto Close Works

Automatic Closing Process

1. Activity Tracking: Monitors tab usage and inactivity periods
2. Criteria Evaluation: Checks if tabs meet closing conditions
3. Protection Verification: Ensures tabs don't match skip rules or whitelist
4. Tab Removal: Permanently closes qualifying tabs
5. History Preservation: Closed tabs remain accessible through browser history

Closing Criteria

Tabs are considered for closing when they:

• Haven't been accessed for the configured time threshold
• Exceed the maximum inactive tab count limit
• Don't match any protection rules or whitelist entries

Configuration Options

Time-Based Closing

Set inactivity duration before tabs are closed:

• Threshold: Configure minutes of inactivity (0 to disable)
• Recommendation: Use longer periods than suspension (60+ minutes)
• Consideration: Closed tabs require manual restoration

Count-Based Protection

Preserve your most recently accessed tabs:

• Protected Count: Number of recent tabs to keep open
• Behavior: When inactive tabs exceed this count, oldest tabs get closed
• Strategy: Set higher than suspension to avoid aggressive closing

Detailed Logic Explanation

"When inactive tabs exceed X, close tabs that haven't been visited for more than N minutes":

Example Scenario: Suppose you have 30 tabs open and set "exceed 15 tabs, close after 60 minutes":

1. Tab Sorting: System sorts all tabs by recent access time
2. Protected Range: Top 16 (15+1) most recently accessed tabs are protected from closing
3. Closing Range: Remaining 14 tabs will be closed if not accessed for 60+ minutes
4. Dynamic Updates: When you access any tab, the sorting updates and protection range adjusts accordingly

Real-world Scenario:

• Tab A: Just accessed (rank #1) → Protected
• Tab B: Accessed 10 minutes ago (rank #5) → Protected
• Tab C: Accessed 3 hours ago (rank #25) → Meets closing criteria, will be closed
• Tab D: Accessed 2 hours ago (rank #20) → Meets closing criteria, will be closed

Differences from Suspension:

• Closing feature recommends larger protection counts (e.g., 15 instead of 10)
• Closing feature recommends longer time thresholds (e.g., 60 minutes instead of 30)
• Closed tabs require manual restoration, so protection strategy should be more conservative

Skip Rules

Choose which tab types to never close:

• Pinned Tabs: Essential tabs that should remain permanent
• Playing Media: Tabs with active audio/video content
• Active Tab: The currently viewed tab in each window
• Form Changes: Tabs containing unsaved form data
• Offline Tabs: Pages accessible without internet connection
• Desktop Notifications: Tabs with notification permissions

Website Whitelist

Protect specific domains from being closed:

• One domain per line format
• Include critical work tools and applications
• Consider email clients, project management tools, and communication platforms

When to Use Auto Close

Ideal Scenarios

• Limited System Resources: Older computers or devices with limited RAM
• Performance Priority: When maximum browser speed is essential
• Minimal Tab Usage: Users who prefer clean, minimal tab bars
• Memory-Constrained Environments: Shared computers or restricted systems

Considerations

• Data Loss Risk: Closed tabs lose any unsaved progress
• Restoration Effort: Requires manual navigation to reopen pages
• Workflow Disruption: May interrupt complex multi-tab workflows
• History Dependency: Relies on browser history for tab recovery

Best Practices

Recommended Settings

• Time Threshold: 60-120 minutes (longer than suspension)
• Protected Count: 10-15 tabs to preserve more of your workflow
• Enable All Skip Rules: Maximum protection for important content
• Comprehensive Whitelist: Include all essential work sites

Workflow Strategies

1. Regular Snapshots: Create tab snapshots before enabling auto-close
2. Pin Critical Tabs: Pin tabs that must never close
3. Monitor Behavior: Watch which tabs get closed to refine settings
4. Gradual Implementation: Start with long thresholds and adjust slowly

Protection Checklist

Before enabling auto-close, ensure:

• [ ] Important sites are whitelisted
• [ ] Essential tabs are pinned
• [ ] Skip rules are properly configured
• [ ] Recent tab snapshots are created
• [ ] Time thresholds are conservatively set

Recovery Options

Restoring Closed Tabs

When tabs are accidentally closed:

1. Browser History: Use Ctrl+H to access and reopen pages
2. Tab Snapshots: Restore from previously saved snapshots
3. Recently Closed: Use browser's built-in recently closed tabs feature
4. Manual Navigation: Navigate back to previously visited sites

Prevention Strategies

• Tab Snapshots: Regularly save snapshots of important tab sets
• Bookmark Important Pages: Create bookmarks for frequently accessed content
• Session Management: Use browser session restore features
• Whitelist Updates: Continuously refine whitelist based on usage patterns

Performance Impact

Memory Benefits

• Maximum Savings: Complete memory reclaim from closed tabs
• System Performance: Significant improvement in browser responsiveness
• Resource Availability: Frees RAM for other applications
• Battery Life: Reduced power consumption on mobile devices

Trade-offs

• Convenience: Less convenient than tab suspension
• Restoration Time: Takes longer to reopen closed tabs
• Data Loss: Potential loss of unsaved work
• Context Switching: Increased cognitive load to restore workflow

Auto close provides the most aggressive memory optimization but requires careful configuration and regular monitoring to avoid disrupting your browsing workflow.
