Features & Capabilities

Tab Counter Plus is a powerful Firefox extension that displays the number of tabs in each window or across all windows, allowing efficient tab management. It offers two display modes—a SVG text icon or WebExtension badge—with fully customizable colors and titles to suit personal preferences.

Unlike other tab counters that continuously query tabs and impact performance, Tab Counter Plus smartly stores tab counts and updates them only on necessary events. It handles multiple windows side-by-side, uses intelligent debouncing to optimize performance during rapid tab changes, and ensures near-instant updates without delays, especially when closing tabs. Built with fast vanilla JavaScript and free of bulky libraries, it provides a lightweight solution. This extension also pioneers a WebExtension feature that boosts robustness and efficiency, making it ideal for users seeking a fast, reliable, and customizable tab counter in Firefox.

Works well, does what I need without noticeable slowdowns at dozens or even hundreds of tabs. I've never run into any issues, never had to dig deep into settings to solve problems. Exactly what I look for in this kind of extension.

Is Tab Counter Plus Safe?

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 Plus 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 Add-ons Store, 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 Plus has earned a fairly good reputation and likely can be trusted.
