Tab Tracker by Web Dev Group

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.
