This works pretty well. They way the hierarchies work is great. My only complaint is that the hierarchy structure gets lost when I close and reopen the browser. I have found a session manager that handles this so I wish it could just be added into Tree Style Tab.

Tree Style Tabs is definitely the best way to handle having a lot of tabs open at the same time.

Hi, dear Pino!

Thank you for your TST. It's very nice and useful/
Unfortunately, I've troubles with Ubuntu FF57: top tab bar doesn't hide. Right side addon's width doesn't change and close tab mark is in left corner, not in right as in previous versions.

Please, fix the bugs.

リリースから結構経ってだいぶ良くなっててうれしい
以下気になっているところ
1. "新しいタブでリンクを開く"アドオンと､"Glitter Drag"アドオンを使っていて､新しいタブを開いた時､1つ下の階層の末尾に子タブが追加されてくれない
1つ下の階層の1番上に追加されてしまう
TreeTabsではちゃんと末尾に追加されるので､多分TreeStyleTabのほうに原因があると思う

2. Ctrl+Tで新しいタブを作る時､今開いているタブの子タブとして開けない
全てのタブの一番下に開かれてしまう

3. セカンドサーチで検索した時､今開いているタブの子タブとして開けない
タブ構造の最末尾に開かれてしまう
要するに俺は全ての結果を今開いているタブの新しい子タブとして開きたい
TreeStyleTabの性格的に筋違いではないと思うしできるようにして欲しい

4. タブが太い
56までの細さのほうが好きです
タブの太さを調節できるようにして欲しい

Very useful. However too few options. I wish there's a way to one-click sort and group all tabs under same URL.

Found it pretty good but why does it force-enable tab containers? This adds another item to the context menu with no option to disable.

Can't live without it. One thing that annoys me is that the trees will sometimes randomly collapse by themselves. I've tried changing some settings but it still does it. cheers!

Very nice, but can't see bookmarks in vertical also. See to Vivaldy layout, two vertical spaces, one for tabs and the other for the bookmarks. If only I could have a shortcut to switch from one to another, at least the lack of seeing both columns at the same time would have less impact.

For years now, trees are easily malfunctioning: many kinds of positional/branch errors or even sticking to a place for no reason.
There should be option for no animation after reordering was requested.
No "unload tree" button exists, not sure if possible.
During last month, a couple of tabs got not clickable, requiring use of keyboard to navigate/close.

VERY Useful! I just wish we could change the look and feel of the sidebar, have thumbnails, and have it Support (as in group them accordingly to...) Mozilla's Multi-Account-Containers. (See https://github.com/mozilla/multi-account-containers/#readme )

Suggest: if it's not possible to auto-hide the TreeStyleTab-Sidebar, would be great showing the tree in a new window, like the Bookmarks Manager window.

Hey!
Can you implement API that allow other extension to integrate into TST? Details https://addons.mozilla.org/ru/firefox/addon/reloadmatic/reviews/996192/

I like it a lot, but I'd like to be able to change the background and text colors and weights of the tabs themselves in Firefox 57/linux. Some of the .css tweaks work, some work in strange ways, and some don't work at all. It was way better before FF57.

Thanks for this add on, it's realy helpfully for user who use a lot of tabs in a session.

I really miss 2 things that wass very usefull, the auto hide, and the transparency without rezize the webpage area.

I don't know if it's posible cus the api limits.

Tree-style tabs are more compact and orderly than organizing tabs through the normal tabs bar. This extension has a few bugs in it, but it's still indispensable to saving time on the internet! Thank you, Piro. :)

Pretty good, only issue is when used with Sync Tab Groups it does not restore the tree structure (the whole view is flattened). That's probably something that Sync Tab Groups has to support, though.
