Tab Black Hole: Tab Limit Manager

Tracking since May 7, 2026.

Changelog

• Jun 5, 2026
  description

  Open 25 tabs at the start of the day. By lunch you can't find the one with the spreadsheet. Switching takes longer than the work.
  
  Tab Black Hole sets a tab limit per browser window. New tabs over the limit go into one tab group at the right end of the tab strip. Nothing closes automatically — you decide what to close and when. Collapse the group if you want it out of sight, expand it to grab a tab back.
  
  A red badge on the toolbar shows how many tabs you're over: +1, +2, +N. Click the icon or press Alt+Shift+B to open the side panel: it lists the overflow tabs, estimates the memory you'll free up by closing them, and gives one click to close all. When overflow reaches +2, an optional in-tab guide opens once a day inside the group — pick tabs with checkboxes and close only those.
  
  Settings, stats, and tab groups stay on your device. Anonymous analytics is off by default — turn it on in settings if you want to help improve the extension.
  
  Use Tab Black Hole as a tab manager, tab limit, tab limiter, tab organizer, tab counter, and tab groups helper for Chrome and Chromium-based browsers. It handles tab overload, too many tabs, browser clutter, and Chrome tabs piling up during research, docs, and articles.
  
  Main features:
  • Tab limit per browser window.
  • Red badge: +1, +2, and higher when a window goes over the limit.
  • Native tab group on the right end of the tab strip — collapse to hide, expand to use.
  • Side panel: cleanup list, current status, estimated memory savings.
  • Keyboard shortcut Alt+Shift+B to open the side panel.
  • Optional in-tab guide with checkboxes, once a day at +2 overflow.
  • Local stats: tabs caught, peak count, days active, current streak.
  • Local-first. Anonymous analytics off by default. URLs, titles, and page content are never sent.

  A red badge on the toolbar shows how many tabs you're over: +1, +2, +N. Click the icon or press Alt+Shift+B to open the side panel: it lists the overflow tabs, surfaces tabs you haven't touched in hours, estimates the memory you'll free up, and gives one click to close all. When overflow reaches +2, an optional in-tab guide opens once a day inside the group — pick tabs with checkboxes and close only those.
  
  Some sites should always be open — your mail, calendar, the task board. Add them to the whitelist and they stop counting toward the limit. From the side panel, one tap next to a tab adds its site; in Options you manage the full list. A domain like example.com also covers its subdomains.

  Most tab limiters do one of two things when you hit the limit: block the new tab, or auto-close an old one. Tab Black Hole does neither. It's a gentler kind of tab limiter — a self-imposed limit that parks the extras instead of slamming the door. Your tabs stay one click away, because the reason people keep too many tabs open is fear of losing something, not laziness.
  
  A calm tab limit and tab counter for Chrome and Chromium-based browsers. Built for tab overload, too many tabs, and forgotten tabs piling up during research, docs, and reading.
  
  Main features:
  • Tab limit per browser window.
  • Red badge: +1, +2, and higher when a window goes over the limit.
  • Native tab group on the right end of the tab strip — collapse to hide, expand to use.
  • Side panel: cleanup list, current status, estimated memory savings.
  • Stale tabs section: tabs you haven't touched in hours, with checkboxes. Threshold adjustable in Options.
  • Whitelist: sites that never count toward the limit — example.com also covers its subdomains. Add from the side panel or Options.
  • Keyboard shortcut Alt+Shift+B to open the side panel.
  • Optional in-tab guide with checkboxes, once a day at +2 overflow.
  • Local stats: tabs caught, peak count, days active, current streak.
  • Local-first. Anonymous analytics off by default. URLs, titles, and page content are never sent.
  
  Recent updates:
  • v1.7 — Whitelist: sites that never count toward your limit
  • v1.6 — Stale tabs: see what you haven't touched in hours
  • v1.5 — Side panel, Alt+Shift+B shortcut, and a memory estimate
  • Now available in 15 languages

  Tab Black Hole is a lightweight tab manager for people with too many browser tabs. It helps with tab overload, tab organization, focus, and productivity by showing a visible tab limit instead of interrupting your workflow. The idea is stress-free tab management: no blocked tabs, no forced closing, and no punishment when you need one more tab right now.
  
  Set your tab limit, browse normally, and watch the red badge when a browser window goes over the limit. Newly opened overflow tabs are gathered into one native tab group at the far right of the tab strip, so extra tabs stay visible, organized, and easy to close.
  
  When tab overload reaches +2, Tab Black Hole can add a local explanation tab inside the overflow group once per day. This guide explains why the group appeared, lets you close selected overflow tabs, and shows where to change the tab limit. You can turn this explanation tab off in settings.
  
  Use Tab Black Hole as a calm tab counter, tab limiter, tab organizer, and tab group helper for Chrome and Chromium-based browsers. It helps you find and close unused tabs, reduce browser clutter, keep Chrome tabs under control, and avoid losing focus when research, docs, articles, search results, and tasks pile up.
  
  Main features:
  • Tab limit per browser window.
  • Compact badge: see +1, +2, and higher when a window exceeds your tab limit.
  • Native tab groups: overflow tabs collect in a visible "Black Hole" group.
  • Tab organizer controls: choose whether pinned tabs and browser pages count.
  • Side panel: see current tab health, recent stats, and a compact cleanup list without leaving your work.
  • Optional explanation tab: learn why the overflow group appeared, close selected overflow tabs, or close all overflow tabs after confirmation.
  • Local progress stats: see how many overflow tabs were caught and how many Black Holes were cleared, stored only on your device.
  • Stress-free tab management: no popups, alerts, content injection, blocked tabs, or forced tab closing.
  • Privacy-respecting productivity tool: settings, stats, and tab groups stay on your device. Optional anonymous analytics, off by default, can be turned on in settings; URLs, tab titles, and page content are never sent.
