Who knew!?

aww yeah, buddy!

Great add-on. Must have item!!!

Obviously cannot be as good as the version prior to web extensions switch by Firefox, but as good as Firefox allows us to have it.

What's up with the reviews? This is an awesome extension and perfect companion to Sidebery/TST.
It works with most of the features in it too restoring the child tabs as child tabs.

The only features I wish existed here were:
--ability to choose which toolbars to hide by default. I do not want the Sidebar in tiled tabs but I DO want the address bar
--ability to have more control over the canvas where the tab tiles create: for example, I want the tab tiles to create over the full window if the window was maximized but if it was not maximized I want it to use the same canvas dimensions excluding the Sidebar.

Great extension, does exactly what is mentioned!

Only suggestion would be to add the option for the layouts to simulating Windows snap splitting. If it the extension made the split windows maximized they would work better with win 11 snap groups

I'm only using the extension to split tabs vertically, and it's exactly what I need.

タブをタイル化して1画面上にたくさん並べることができる拡張。Emacsのsplit-windowのようにウィンドウにタブを敷き詰めることができる。具体的な操作方法として、ウィンドウを上下2分割するには、ツールバーのアイコンを右クリックメニュー→Manage Layout and Tiles→Default Layouts→2 Tabs horizontalを選び、分割したいタブを表示させてアイコン右クリックメニュー→Tile Tab→belowで下に表示したいタブを選ぶと、アクティブタブとそのタブだけが抽出されて、上下に分割表示される(Emacsのsplit-window-verticallyと同じ) 。タイル間はCtrl-Tabで移動でき、アイコンのクリックもしくは「Shift+Alt+↓」(分割オン/オフのトグルキー)を押すとウィンドウ分割がオフになる。Manage Layout and Tiles→Sync Scrollをチェックすれば各タイルを同期してスクロールさせることもできる。
エディタ側でブログなどの記事の構成順を前後に再配置する際に、再配置したい記事の該当箇所が複数箇所に離れて散在する場合に、その場所をブラウザ側でも確認しながら編集したく、ブラウザの上下2分割表示が実現できるアドオンを探していたので、とても助かった。

This does exactly what it says - opens existing tabs as arranged and synchronized browser windows- and does it perfectly.

You can easily turn off the toolbar across all windows, syncronize scrolling between them, and realign them if you disturb the original configuration. You can set a default layout, and pick a different one at any time. The menus are clear and intuitive. It will close the splits as easily as it opened it, restoring them all to tabs.

I love this add-in! Thank you developers!

Excellent!!!

It works. I have tested it on 04-12-21-_01_55_36_a_Mon

很优秀的扩展, 这就是我想要的。

One of the best!

Cette extension fait bien son job comme le "Tab resize" dans Chrome, super content de retrouver la même fonction dans Firefox.
