Features & Capabilities

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

Tab Counter is a simple, unobtrusive addon that clearly shows open tab counts and helps identify windows with many tabs. Users value its minimal footprint and single-purpose utility. Common complaints focus on a 3-digit limit, truncation for large counts, and a lack of customization (font size/format). A few reports mention performance slowdowns. Overall, the addon is useful, but users want scalable numbers and more configuration options.

Pros

Easy to see open tab counts.
Lightweight, single-purpose, unobtrusive addon.
Helps identify which window has the most tabs to prioritize closing.

Cons

3-digit limit; cannot display 1000+ tabs.
Numbers can be truncated or don't fit on screen for large counts; requires hovering or workaround.
Lack of customization options (font size/format) to fit the UI.
Potential performance slowdowns reported by some users.

Simple. I use either this one or Tab Count, they do the same. If I could know which one is the lightest, I would use.

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