とても便利に使えていますが、大量にタブを抱えていると落ちて復旧するときにツリー構造が破壊されることがある感じがします。
上のほうにあったタブ群が下に来たり、子タブがぶら下がってるタブがただのフォルダのようになって内容が復帰しなかったり、その子タブの一番下のタブを閉じるとなんか反応があったり。
Tab Session Managerとの併用なのでどちらの問題なのかはよくわかりません。

Так изуродовать прекрасное дополнение ... Это надо было приложить массу усилий.

Firefox 57 has completely ruined this add-on. Highly unfortunate as I read online to see if there would be any issues before updating and it didn't look like it would be a problem.

Расширение не убирает горизонтальные вкладки. Итого: дублирование информации и лишнее место на экране.

The extension doesn't remove horizontal tabs. So, just doubling info and takes odd place on screen.

La idea de las pestañas de estilo arbol es reemplazar a lo incomo que es el tener tantas pestañas en la parte superior, ahora no se ocultan como en versiones pasadas de firefox, una pena de verdad llevo añños usando la extension, parece que esta perdiendo el sentido

Kein Ersatz für Tab Mix Plus aber wenigstens läuft es im neuen Firefox 57 (Quantum)

Why are so much permission required lately? It's asking right now for every data everywhere and it's kind of freaking me out..
I find this extension very usefull thought

Requires access to ALL data from websites! I think I'll pass thanks

I am addicted to this extension since 2.5 years and suddenly firefox updates screws it. It is showing tabs in both horizontal way and tree style. Now I am stuck with a weird looking UI. Had to disable.


PLEASE REMOVE THE OLD WAY OF SEEING TABS. FFS

It shows the old tab view AND the tree style tabs at the same time when using it with Firefox 57. I had to disable it, but I'd really like to use it again.

"Tree style tab" is the reason why i'm on firefox. Unfortunately, this new version is the reason why i switched to Firefox-ESR until this becomes usable.
