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

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
