タブが表示されなくなることが多々ありますそれさえ直れば完璧です。

Didn't like it, removed.

buggy, breaks youtube

Might be useful but looks like trash. Uninstalled immediately

Какойто идиотизм высшей пробы. Последнее дополнение убрало возможность перемещать вкладки чтобы делать дерево. И как теперь это сделать? Те что были раньше есть. А новое дерево сделать нельзя. Вкладка не помещается под главную...
Идиотизм

I coundn't live without it during years. But now, Too much reported bugs that never get fixed, too much CPU & RAM hog, need to install TST addons, with reported bugs that never get fixed.

SideBery is way better, and stable !

I installed it on the advise of a friend and the tree suddenly started flickering! I disabled Tree and other common extensions and it stopped. I put all of them back on and it has not been flickering. I am not sure what caused it.

It was a great add-on and helper to work with. But recent updates have bring serious delays, freezes, and the termination of the browser. Unfortunately, the convenience was lost against the background of unstable work. With the latest version, my 40 tabs opened only after the third time by restarting the browser.

Standard Tree Style Tab funktioniert nicht, die anderen Funktionen jedoch schon. (FF 104.0.1)

I really like what this add-on does. The problem is that it never stops doing it. I have tabs that need to be in a tree structure. That part is great. But I don't want new trees created every time I run a Google search or open a new tab from an existing page. Sadly, there seems to be no way to control that. So if I want to use this add-on at all, I have to manually flatten every newly created tree. It is a chore, and it seems unnecessary.

This is (or was) one of my favorite extensions, but then they decide to remove one of the most fundamental and needed features: grouping. It's a basic feature that should be in this main extension, and not in a separated one!!! The developer must have their decision reasons and probably related to maintenance burden... Still I'm kind of disappointed and pretty much lost at least 2 of 5 stars with this removal.

Gute Idee, schlecht umgesetzt (z.Bsp. können Knoten/Root nicht umbenannt werden).

Die Anordnung mit vertikaler Baumstruktur erfolgt völlig willkürlich. Ih empfinde das als sinnlos und macht die Tabs unübersichtlich. Es wäre besser keine vertikale Baumstruktur aufgezwungen zu bekommen.

I get that it's more practical but as long as it is not possible to hide the top bar you end up with double the clutter.

It would be great except it's not impossible under any circumstances to remove the existing tab bar in any way. I tried creating a userCrome.css file since that appeared to be the only way but to no avail. If I have no choice but to have a top tab bar there is no point in having your addon. Shame.

This plugin does a thousand different and strange things like open special tabs to just create a fancy tree, and I just want a simple sidebar.
