This helps browsing a lot, but it does have a few bugs. Right now, I'm experiencing a bug where the tabs have been slightly truncated, chopping off the favicons.

Very outstanding addon, but since 2 months it's super slow. When disabled Firefox is working fine. But enabled it slows so much down that Firefox is nearly unuseable.

cool function "close other tabs"
always got on her instead "reopen closed tab"

Хорошее приложение но не информативное. Практически нет разници между поиска в горизонтальном меню или вертикальном. Древовидный вид мне нравится, но сейчас Tree Style Tab не использую.

Минусы:
Не информативное. Ничего не добавляется от бокового расположения. О том, что в моем представлении должно добавиться, будет ниже
Загромождает дополнительное пространство. Сюда же. Не убирает горизонтальное меню (не знаю возможно ли это, это ИМХО)

Плюсы:
Более удобный поиск вкладок благодаря древовидному виду
Вкладви сбоку и это удобно:)

Мое представление
Древовидный вид сохранить, но сделать без сдвига, что бы добавить картинку того, что расположено на сайте. Добавить возможность переключится на вид без картинок;
Добавить сохранение/восстановление вкладок отдельного окна. Кстати из-за того, что для этой функции использовал сторонний плагин, Tree Style Tab пришлось удалить. После восстановления вкладок, не восстанавливался древовидный вид:(

please add auto hide in specific time and when mouse come to corner of screen show column again
thank you

I think this is a good extension for organization of work, but "header" tabs would be nice to sort projects, e.g. fake tab for "project 1" or "project 2"

I liked the functionality of this extension a lot, but it slowed my Firefox to a crawl... like 6-8 seconds for a click to register. I had about 20 other addons, so there may have been conflicts. I decided to uninstall it for now and switched to Tab Center Redux.

I like the concept and the customisability. What does not work well is pinned tabs. When Firefox is closed and reopened the pinned tab is gone.

Great addon, but tabs got scrambled once in a while, which completely messes everything up. It's not happening very often, but when it happens, you need to spend a lot of time to fix it.

Great extension! I love being able to organize my tabs in this way, have been using this for a few years now.

Minor complaint:
The recent update that recently (I think?) introduced keyboard shortcuts that interfere with nominal text editing, e.g. Ctrl + Shift + Left/Right, which I use for highlighting words.
The keyboard shortcut editor is generally buggy, as I can't figure out how to disable a key; trying to set it to something useless, like Ctrl + Shift + / or pressing ESC, doesn't work; I can only sometimes set it to "undefined".

May just jump directly to wherever the config lives and kill the keys.

EDIT: Hup, it's already filed and fixed - awesome!

I love this Add-On... use it and abuse it...
It does take a bit of practice and learning, but it sure works for me...
Only thing I hate is... I can not get rid of the Tab Bar at the top of the browser...I see no point in having it there....
Is there a way to turn it off?

This is great if you have opened like 10 more tabs.
But I love to auto show/hide if it more than xxx tabs open.
Is this possible?
