Description
Shows the tab order number (1–9) before the title on the first 9 tabs in each window. Useful for Ctrl/Cmd+1–9 switching. Tab Numbers ➀–➈ — See the first nine tab numbers at a glance Jump between tabs faster and with fewer mistakes. This extension adds a bold, high‑contrast dingbat number (➀–➈) to the beginning of the first nine tab titles in each window—perfectly matching the built‑in shortcuts Ctrl/Cmd + 1–9. No clutter, no distractions—just the number you need, right where your eyes look. Why you’ll love it • Instant orientation. Know which tab is “tab 3” or “tab 7” without counting from the left. • Made for shortcuts. Numbers map to the browser’s native tab switching (Ctrl/Cmd + 1–9). • Big and legible. Uses Unicode dingbats (➀–➈) that are larger and easier to see than superscripts. • Automatic and lightweight. Updates whenever tabs are opened, moved, or closed—no manual refresh needed. • Toggle anytime. Press Alt+N to show/hide numbers (customizable in Chrome’s keyboard shortcuts). • Per‑window awareness. Applies to the first nine tabs in each normal window, just like the keyboard shortcuts. How it works (under the hood) A small background service worker listens for tab events (create, move, remove, activate, window focus, etc.). When something changes, it sends the appropriate prefix to a tiny content script in that tab, which adds the digit to the start of the page title. If a site changes its <title>, the extension re-applies the correct number automatically so the marker stays consistent. Important: This extension only modifies the tab title. It does not access page content beyond the document title and does not send any data anywhere. Permissions & privacy Requested permissions • tabs – Needed to know tab order and update the right tab. • host permissions: <all_urls> – Required for the content script to add the number to the page’s title. Privacy • No sign‑in, no analytics, no ads, no tracking. • No data collection or sharing. Nothing is sent to external servers—everything runs locally in your browser. • The extension modifies only the tab title to display ➀–➈ and does nothing else to page content. Keyboard shortcuts • Windows/Linux: Ctrl + 1–9 to jump to tab 1–9; Alt+N toggles the numbers on/off. • macOS: Cmd + 1–9 to jump to tab 1–9; Alt+N toggles the numbers on/off. You can change Alt+N via chrome://extensions/shortcuts. Known limitations • Restricted pages: Chrome doesn’t allow extensions to modify some pages (e.g., chrome://* and the Chrome Web Store). Those tabs won’t show numbers. • Pinned tabs: Chrome hides titles for pinned tabs, so you may not see a number even though the tab is counted in the order. • Incognito: To use in incognito, enable “Allow in incognito” on the extension’s details page. • Tab 10 and beyond: Chrome’s built‑in shortcuts cover only 1–9 (9 goes to the last tab). This extension mirrors that design. Troubleshooting • “I don’t see any numbers.” – Make sure the extension is enabled. – Try toggling with Alt+N. – If on a restricted page (chrome:// or Web Store), try another website. – If you just installed, reload a couple of tabs to trigger the first refresh. • “The number disappeared after the site changed the title.” – The extension re-applies automatically. If a site is very aggressive about changing titles, a brief delay may occur; the number should reappear momentarily. • “Another extension also edits titles.” – If numbers don’t appear or look duplicated, check for other title‑editing extensions and adjust their settings or disable one of them. Lightweight by design • Event-driven: The background service worker sleeps when idle, waking only for tab/window events. • Tiny footprint: Minimal code with a narrow, well‑scoped purpose. • No network access: Works fully offline; never contacts external servers. What’s included • Dingbat numerals ➀–➈ prefixed to tab titles 1–9 in each window. • Automatic updates on tab create/move/remove/activate and window focus changes. • Title‑change resilience via a small MutationObserver. • Toggle via Alt+N (configurable). • Toolbar click to trigger a quick refresh (optional convenience). FAQ Q: Why use dingbats (➀–➈) instead of superscripts (¹–⁹)? A: Dingbats are larger and typically render with clearer shapes in tab bars, making them easier to spot in a hurry—especially on smaller laptop screens. Q: Does this slow down my browser? A: No. It’s event-driven and only touches the tab title string. There’s no heavy DOM work or network activity. Q: Will it reorder or renumber tabs automatically when I drag them around? A: Yes. As soon as a tab’s position changes, the numbers are recalculated and refreshed. Q: Can I change the keybinding? A: Yes—go to chrome://extensions/shortcuts and set any shortcut you like for “Toggle tab numbers.” Changelog 1.0.0 • Initial release with Unicode dingbat numerals ➀–➈ • Automatic updates on tab and window events • Title‑change resilience • Alt+N toggle
