Winger

In case you switched to Firefox from a Chromium-based browser, then one of the things that you are probably not happy about is the tab management. The perfect tab management solution continues to evade the Firefox browser, but luckily there are numerous extensions out there that provide a solution to this problem.

Winger is a Firefox extension that enhances and extends the built-in window management capabilities.

For starters, the extension enables you to create customizable windows that you can name based on various criteria, including topics, tasks or projects. The GUI is designed with simplicity in mind and presents windows as a clear list of names, enabling you to quickly browse and locate the desired window. The intuitive interface facilitates effortless filtering, making it convenient to find specific windows even in cases of numerous open tabs.

As far as management goes, everything is just a click away, and you can easily name your windows, switch between them, and move tabs with minimal effort. Overall, the feature allows for efficient organization and helps you keep track of their tabs in a more structured manner.

The extension offers convenient ways to move tabs between windows, providing you with the flexibility to choose between ‘send’ and ‘bring’ actions. You can customize key bindings for these actions, ensuring a predictable and personalized tab management experience. Moreover, it supports the seamless transfer of tabs between private and non-private windows, automatically reopening them in the appropriate context.

According to the developer, the add-on is not exactly a tab management tool, although it operates in the same realm. Rather than introducing a new tab collection concept, Winger utilizes windows, which are efficient and original "tab groups" with all the familiar features of your browser and operating system.
