Tab Counter

Add a badge to the toolbar that shows the number of currently open tabs in a window or all windows.

Tab Counter is a handy Chrome extension that adds a badge to your browser toolbar displaying the number of currently open tabs in a window. You can click the badge to view the total number of open tabs across all windows. Customize the badge color and text color (supported in Firefox v63+) to fit your preferences. The extension also allows configuring what the badge counts—tabs in the current window, tabs in all windows, total windows, or none, with a popup for details.

Built as a WebExtension, Tab Counter supports modern browsing with e10s compatibility and works seamlessly in Firefox 57 and above. Its clear icon option helps display only the tab count, keeping the toolbar clean. This extension is perfect for users who want quick and easy insight into their tab usage and window management.

User reviews

Users appreciate Tab Counter as a simple and lightweight tool that clearly shows the number of open tabs with a minimalistic interface. It helps in managing browser clutter and is memory-efficient. However, many reviews point out the limitation of displaying only three digits, causing counts above 999 to be truncated. Users also desire more customization options like adjusting font size and display length. Some have noted performance slowdowns when having a very large number of tabs open.

Extension safety

Risk impact
Risk impact measures the level of extra permissions an extension has access to. A low risk impact extension cannot do much harms, whereas a high risk impact extension can do a lot of damage like stealing your password, bypassing your security settings, and accessing your personal data. High risk impact extensions are not necessarily malicious. However, if they do turn malicious, they can be very harmful.

Tab Counter does not require any sensitive permissions.

Risk impact analysis details
    Risk likelihood
    Risk likelihood measures the probability that a Firefox add-on may turn malicious. This is determined by the publisher and the Firefox add-on reputation on Firefox Browser Add-ons, the amount of time the Firefox add-on has been around, and other signals about the Firefox add-on. Our algorithms are not perfect, and are subject to change as we discover new ways to detect malicious extensions. We recommend that you always exercise caution when installing a Firefox add-on.

    Tab Counter has earned a fairly good reputation and likely can be trusted.
