FAQ & Support

Two likely reasons:

1. You haven't reloaded the existing tabs. TabTint only runs on tabs that were opened or refreshed after installation. Hit Ctrl+R (or Cmd+R on Mac) on the tabs you want it to affect.
2. The master toggle is off. Click the TabTint icon in the toolbar and flip the toggle at the top-right of the popup.

Once both are true, switching between reloaded tabs should show the active marker and the dimming effect immediately.

Only when Chrome fully reloads the extension (install, update, manual disable/enable, or browser restart). After that, any tab already open when the reload happened will need a refresh for TabTint to start running on it. New tabs work automatically.

Click the TabTint icon in your toolbar to open the popup. You'll see a 5×2 grid of colors (including a rainbow + chip for a custom hex), a dropdown for the active-tab favicon style, and two sliders for inactive-tab dimming and title shortening. Changes apply live — no reload needed once TabTint is running on the tab.

• Replace — solid colored circle replaces the site favicon.
• Corner dot (default) — original favicon with a small colored dot at the bottom-right.
• Ring — colored ring around the original favicon.
• Side bar — thin colored stripe on the left of the favicon.

Anything built on Chromium 114 or newer — that includes Google Chrome, Microsoft Edge, Brave, Opera, Arc, and Vivaldi. Firefox and Safari are not supported; they use different extension APIs and would need separate builds.

Chrome blocks all extensions from modifying those pages — that's a browser-level security policy, not a TabTint limitation. The extension has no effect there, and there's no workaround.

Yes. TabTint changes the favicon image and the document title — anything that displays those two things (vertical tab sidebars, tab-group pickers, tab search UIs) gets the treatment automatically.

No — TabTint watches for that and re-applies its marker on top. You may see a brief flicker when the site updates its icon (say, when a new email arrives), but TabTint should reassert its overlay within a moment.

If you see a site where TabTint permanently loses the battle, please get in touch with the URL so it can be looked at.

That's the title-shorten slider at 100%. Drop it lower and the titles will come back proportionally — at 50% you get roughly half the characters, at 0% the full title.

Not right now. TabTint uses one color for whichever tab is currently active. Per-site colors are on the maybe-someday list — if you want to weigh in, drop a note via support.

The content script is small (under 10 KB), runs only on tab activation or settings change, and does all its work on a 32×32 canvas. You shouldn't notice any impact.

Disabling the master toggle restores every tab's original favicon and full title immediately. Uninstalling removes the extension along with all stored settings — nothing lingers on your system.

Because the whole point of the extension is to change the favicon on every tab you have open. That requires a content script on every site. It reads the favicon URL and the page title — nothing else. Full details in the privacy policy.

No. No analytics, no crash reporting, no account, no server. Settings live in Chrome's local storage on your device. The extension never makes a network request of its own.

No. TabTint uses chrome.storage.local, which stays on the current device. This is deliberate — no cross-device telemetry, no cloud account required. Configure each install independently.
