More powerful than any competitor, but doesn't adhere to the colouration of the system as well as addons.mozilla.org/firefox/addon/tree-style-tab does, per github.com/mbnuqw/sidebery/issues/952#issue-1592410166.

Great so far, but why can't I use the command key for keyboard shortcuts?

Nice better than Tree Style tab add-on.
But there is a small problem when opening browser for the first time, it freezes the whole firefox, can't choose tabs & need to restart it couple of times so it can load normally. Hope you will fix it soon.

Muy Buena extencion

Лучшая панель вкладок которую я видел.

It looked fantastic, until I got no scroll bar and more tabs than fit vertically :( Thank you anyway, it probably works fine elsewhere.

The addon is excellent, but I would like to add the function of automatic collapsing of grouped tabs over time.
Now you have to do it every time in order to free up your free space.

Absolutely wonderful and should come stock with every browser! However, I would really like to see a search function implemented so that I can quickly and easily find a specific tab in a window (If this option exists then I could not find it)

This should be the second add-on that you install after uBlock.

The customizability is quite intimidating, but once you get it dialed in it's a browser experience that is unmatched.

Huge thank you to the author for creating this, and for putting the source on GitHub. People like you are the reason that open source works.

It's usefull
