This extension has become a must in my workflow! I love being able to group my tabs and have quick access. When I don't want to be distracted by a topic, I simply collapse the group and the clutter goes away. It also helps with Firefox's memory management by unloading tabs in the collapsed groups.

I had an issue with Zen browser and Sideberry where all the tabs disappeared. That was 6 months ago and I believe it was more related to Zen than the extension. Since using Sideberry with Firefox directly, I've managed to keep all my tabs. I also like the automatic backup feature!

Thanks to all the devs of this fantastic extension!!!

works flawless, love it

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

Tree style tabs convert. It works great, and the amount of customization available in the settings is insane. This extension is very impressive.

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.
