## Description

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.

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.
