I ditched Google and came back to Firefox because of this extension. It works perfectly with groups. Just what I was looking for to organize my online life.

Tuyệt vời

Good extension with giant amount of tweaks! The only thing to developer – I'd like to control background color or even hide top header with "Tabs > X" at all.

Thanks

Finally something better than than Tree Style Tab! Well done!

非常好用的扩展。但我想知道未来的更新可不可以加入这个功能：当鼠标指针不在侧边栏区域时，侧边栏自动收缩，只显示网站的图标；当指针移动到侧边栏区域后，侧边栏变宽，且显示的内容变多。
就像Edge的垂直标签页一样

强大无比

Level up my FF experience.

Locking a tab panel/ container would be great

Finally a powerful, easy to use tab-management solution. Just amazing.

Amazing extension; makes window groupings much easier to manage, and automatically sorted pages mean it's much faster to navigate between a lot of pages, for increased productivity and convenience.

Also very nice to be able to scroll through tabs and have it change through tabs very quickly; makes changing tabs very easy.
Another nice thing is the option to 'lock' the scroll to a specific grouping for focused work.

Overall very well thought out extension, with a lot of great optional, and automative features
