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

Clicking the Add button when all tabs are cleared does not add tabs properly.

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

Installed this extension a few months ago and never looked back. Got rid of the native tab bar at the top also. Whilst the default settings are good already, take your time to go through the settings and configure everything to your liking.
