TreeTabs od Taras

The TreeTabs extension provides a system for managing and storing the hierarchy of your browser windows and tabs (the state), ensuring that no data is ever lost. This state can be transferred to another device (with TreeTabs installed) — this allowing you to pick up exactly where you left off, with your windows and tabs configured just as they were.

If you frequently work with a large number of browser tabs, TreeTabs is an essential tool to help you stay organized.
TreeTabs maintains high performance even when handling tens of thousands of items!

TreeTabs enables you to manage the context of your current windows and tabs; its import and export features not only help you structure your browsing workflow but also allow you to share your tab setups or archive your browsing context.

TreeTabs supports drag-and-drop functionality, allowing for handly management of your tab structure. Each item within this structure offers useful options accessible via a context menu or keyboard shortcuts — for instance, you can name a group of tabs or rename an individual tab. Furthermore, the program’s interface and core features are highly customizable; this is particularly convenient if you wish to adjust the size of specific elements, select a different interface language, or change the color scheme.

The TreeTabs interface is multilingual and supports English, French, Ukrainian, Spanish, Portuguese, Finnish, German, Chinese, Russian, and a large group of Arabic languages.
