Давно пользуюсь, очень удобно!
Переоткрытие некоторых сайтов в новый таб с настроенным контейнером - вообще огонь!

К дереву вложенности вкладок быстро привыкаешь, особенно когда долго ищешь, а так всё наглядно получается.

Жалко, только запарно выключать стандартные табы в firefox, выключались бы они кнопкой, а не стилями в .css

Love it, wonderful for Tab grouping and saving

One of the best tools to manage tabs, bookmarkers and most everyday need related to web.

I can have four million tabs and still be organized.

Great addon, I just wish it would work in private mode, without needing to hit F1 to make it show.

Great addon to save yourself the headache of figuring out how to split firefox into multiple windows on start across your workspaces or multiple instances.

Awesome organizing addon, lots of options to set it up perfectly to overcome what Firefox lacks. Recently coming from the Chromium world after a long journey there, I forgot how underdeveloped Firefox can be, but addons like this are here to fix that and more, make it even better. Great job!

A versatile extension that does many jobs, and does them all well. The best one I've used to organize my tabs so far!
