Tab Black Hole: Tab Limit Manager

A tab manager for tab limits, tab groups, tab overload, focus, productivity, and organizing too many browser tabs.

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. 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, how to close extra tabs, and 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.
