Tab Tracker by Web Dev Group

Big, sharp live tab counter right on your toolbar. Duplicate detection with review, daily peaks, search. By WEB DEV GROUP LTD.

THE NUMBER IS THE ICON. MONITOR HOW MANY TABS YOU HAVE OPEN IN REAL-TIME! Tab Tracker counts and manages the tabs open in the user's browser. It shows the live count directly in the toolbar icon, tracks daily and all-time peaks, and finds and closes duplicate tabs. Tab Tracker replaces its own extension icon with your live tab count — big, black, always readable. No tiny corner badge. No cramped overlay. Just the number, sharp at every DPI, in every browser theme. Built by developers, for developers. If you keep 40+ tabs open across multiple windows, this is the extension you have been looking for. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ KEY FEATURES ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ ▸ THE NUMBER IS THE ICON Solid black background, big white digits. The icon repaints every time the count changes, at 16 / 32 / 48 px, in under a millisecond. ▸ THRESHOLD COLORS THAT MEAN SOMETHING White by default. Amber at your warn threshold (default 25). Red at your alert threshold (default 50). Every threshold is configurable. ▸ DUPLICATE REVIEW WITH SIDE-BY-SIDE COMPARISON Tap the duplicates stat (or open Settings) to see every duplicate group with the original marked KEEP and the extras marked DUPLICATE. Close all, close a whole group, or close a single tab. Nothing happens until you confirm. ▸ SMART URL MATCHING Strips utm_*, gclid, fbclid, mc_*, _ga, msclkid, then sorts remaining params so ?a=1&b=2 matches ?b=2&a=1. No false negatives from tracking noise. ▸ PINNED TABS ARE PROTECTED Pinned tabs are never flagged as duplicates and never closed. Guaranteed. ▸ KEEPER PRIORITY When closing duplicates automatically, Tab Tracker keeps: the active tab in your focused window → any active tab → the oldest tab. Predictable, every time. ▸ DAILY + ALL-TIME PEAK TRACKING See today's peak and your all-time peak in the popup. History auto-prunes after 90 days. ▸ INSTANT SEARCH Search by title or URL across every window. Click to jump. Press / to focus. Esc to clear. ▸ PER-WINDOW GROUPING Current window highlighted, incognito flagged, discarded and idle tabs marked. ▸ KEYBOARD SHORTCUT Configurable at chrome://extensions/shortcuts. Default: Ctrl+Shift+D (Cmd+Shift+D on Mac) opens the popup. ▸ SETTINGS PAGE Configure warn / alert thresholds, review duplicates, reset peaks, and opt in or out of notifications. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ PRIVACY — YOUR TABS STAY YOURS ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ Tab Tracker is 100% local. Zero network calls. Zero analytics. Zero third parties. Zero tracking. ▸ No remote code. ▸ No cloud sync of URLs. ▸ No telemetry, no crash reports, no fingerprinting. ▸ Favicons are served by Chrome's native favicon cache (_favicon API) — never an external service. ▸ Data lives in chrome.storage.local on your machine. If it looks like Tab Tracker is doing something on the network, it isn't. Open the network tab, we'll wait. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ BUILT TO BE BULLETPROOF ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ ▸ Manifest V3, service worker, strict CSP. ▸ Debounced updates — every tab event is coalesced so nothing thrashes the icon. ▸ Serialized peak writes — no race conditions when tabs open in bursts. ▸ Auto-pruned storage — 90-day history rolling window. ▸ Validated messaging — invalid messages from any content script are rejected. ▸ Minimum Chrome 108 — uses OffscreenCanvas in the service worker for dynamic icon rendering. ▸ 53 unit tests covering URL normalization, keeper selection, close planning, icon text formatting, and threshold color selection. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ PERMISSIONS EXPLAINED ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ ▸ "tabs" — required to read tab titles, URLs, and window info so we can count, group, search, and detect duplicates. We never transmit any of this. ▸ "storage" — stores your settings and peak counts locally in chrome.storage.local. Nothing leaves your device. ▸ "favicon" — uses Chrome's native _favicon API to render favicons without third-party requests. ▸ "notifications" (optional, opt-in) — surfaces threshold-crossing alerts only if you turn them on in Settings. Tab Tracker does not request host permissions. It cannot see or modify any web page you visit. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ WHO IS THIS FOR ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ ▸ Developers running multi-project browsers with 50+ tabs. ▸ Researchers, students, and PMs juggling multiple sources. ▸ Anyone who has ever typed "how many tabs do I have open" into a search bar. ▸ People who value privacy and want an extension that does one thing well. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ BY WEB DEV GROUP LTD ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ Tab Tracker is built and maintained by WEB DEV GROUP LTD — https://webdev.com Feedback, bug reports, and feature requests: use the support link on the store listing.
