## Description

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.
