Tab Black Hole: Tab Limit Manager

Stop drowning in tabs. Set a limit — extras gather in one quiet group, never auto-closed. Install and breathe.

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, 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. 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. 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.
