What is Tab Wrangler?
Tab Wrangler is an intelligent tab management extension that automatically closes inactive tabs while preserving easy access to everything you've viewed. With over 200,000 active users and a 4.5/5 rating, it solves the chronic "tab overload" problem that plagues power users, researchers, and multi-taskers who routinely accumulate 30-100+ open tabs, causing browser slowdowns, memory exhaustion, and lost productivity.
The extension works by monitoring tab activity and automatically closing tabs that haven't been viewed for a configurable period (default 20 minutes). Unlike simply closing tabs permanently, Tab Wrangler saves every closed tab's URL and state to a "Recently Closed" list accessible from the extension icon. Click any entry to instantly restore the tab exactly as it was - no searching through browser history, no lost context. This creates a perfect balance: your active tab count stays manageable (typically 10-20 tabs), but you retain instant access to 100+ recently viewed pages.
What makes Tab Wrangler indispensable for power users is its intelligent auto-close logic. The extension never closes pinned tabs, active/focused tabs, tabs playing audio or video, or tabs with unsaved form data. You can also whitelist specific domains (like Gmail, Slack, project management tools) that should remain permanently open. This smart filtering ensures Tab Wrangler only closes truly inactive research tabs, reference pages, and background reading - never your critical work tabs.
Beyond auto-closing, Tab Wrangler provides searchable tab history, bulk tab restoration, export/import of saved tabs, and detailed statistics showing how many tabs have been wrangled and how much memory has been freed. The extension typically frees 100-500MB of RAM by closing inactive tabs, dramatically improving browser performance on machines with limited memory. For users who compulsively research topics and end up with 50-200 open tabs, Tab Wrangler is the difference between a sluggish, unusable browser and a fast, efficient workflow.
Key Features
Auto-Close Inactive Tabs
Automatically closes tabs after configurable inactivity period (5 minutes to 24 hours, default 20 min). Saves tab URL and state before closing - nothing is permanently lost. Never closes pinned tabs, active tabs, tabs with audio/video, or tabs with unsaved forms. Smart filtering ensures only truly inactive tabs are closed.
Restore Recently Closed
Click the Tab Wrangler icon to view all recently closed tabs (default 100 max saved). One-click restoration brings tabs back exactly as they were. Search through closed tabs by title or URL. Export saved tabs to JSON for backup or import on other machines. Clear old entries manually or set automatic expiration.
Whitelist Important Sites
Prevent specific domains from auto-closing using flexible whitelist patterns. Add exact domains (gmail.com), wildcards (docs.google.com/*), or regex patterns. Perfect for keeping email, messaging, project tools, or always-needed sites permanently open. Whitelist takes priority over all auto-close rules.
Save Tab State & Memory
Saves tab scroll position, form data (when possible), and URL fragments before closing. Frees 100-500MB+ of RAM by closing resource-heavy tabs (news sites, social media, image galleries). Most users report 15-30% faster browser performance and reduced lag when Tab Wrangler maintains active tab count under 20.

Tab Wrangler excels at automatic tab management with time-based auto-close and flexible restoration. OneTab requires manual triggering but is great for one-time bulk tab saving. The Great Suspender keeps tabs visible but suspended - less memory savings but maintains tab bar context. For hands-off automation with maximum memory recovery, Tab Wrangler is the superior choice.
Frequently Asked Questions
How does Tab Wrangler auto-close tabs without losing data?
Tab Wrangler saves tab URLs and state to browser local storage before closing. Closed tabs appear in the 'Recently Closed' list accessible from the extension icon. Click any entry to instantly restore the tab exactly as it was. Tab Wrangler never auto-closes pinned tabs, active tabs, or tabs with active forms/media, ensuring important work is never lost. The extension saves up to 100 recently closed tabs by default (configurable).
What is the recommended inactivity timeout for Tab Wrangler?
Default timeout is 20 minutes, which works well for most users. Power users with 50+ tabs often use 10-15 minutes, while casual browsers prefer 30-60 minutes. The timeout starts when you switch away from a tab - so if you're actively reading for 30 minutes, the tab won't close. Experiment to find your ideal balance between memory savings and convenience. Start with 20 minutes and adjust based on how often you need to restore closed tabs.
Can I whitelist specific websites from auto-closing?
Yes, Tab Wrangler supports flexible whitelisting. Add specific domains (e.g., gmail.com), URLs with wildcards (e.g., docs.google.com/*), or entire URL patterns to the whitelist. Whitelisted tabs never auto-close regardless of inactivity. Perfect for keeping email, messaging apps, project management tools, or other always-open sites permanently available. Access whitelist settings by right-clicking the Tab Wrangler icon → Options → Tab Lock.
Does Tab Wrangler slow down Atlas Browser?
No, Tab Wrangler actually speeds up Atlas Browser by reducing active tab count and memory usage. The extension itself uses <5MB memory and minimal CPU. By auto-closing inactive tabs, it can free 100-500MB+ of RAM depending on tab content. Most users report 15-30% faster browser performance and reduced lag when switching tabs or opening new ones. Tab Wrangler solves performance problems rather than creating them.
