As other people have noted not sure why the reviews skew to low for this extension - it does what it says and I've found it very useful for using multiple tabs simultaneously. Only thing keeping it from 5 star from me is the Toggle Toolbars option appears to be breaking the tiling layout - can't seem to see a way around this.

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!

I was expecting multiple tabs tiled into a single window, not multiple browser windows all over my desktop each with a toolbar that eats up space.

Yeah, not sure what all those bad reviews are on about... They seem to be pretty old; there should be a way of discounting ageing reviews. Anyway, my only grievance is not having keyboard shortcuts for expanding and contracting a tile, instead of having to click-click-clicking every time. Otherwise, I'd give it a 5.

Excellent!!!

I feel bad for the author that this extension has such a low rating, which seems to stem mostly from people who review-bombed it years ago over limitations Mozilla implemented.

I will say that the overall UX is not super intuitive, but as a web developer working with multiple windows at various viewport sizes, having adjacent windows readjust themselves is such a timesaver.

Until FancyZones implements this feature (https://github.com/microsoft/PowerToys/issues/254), this is a great free browser alternative to tools like AquaSnap.

Thanks DW!

Extremely useful, and a very important add on for me! Thanks to the developers for making this! Works flawlessly without any problems! Grateful for your hard work!

I like this extension very much and I have been stuck in the 11.15 version. Because the new version close tab will close all tabs, instead of 11.15 version only closes the tab that I clicked to close. For this reason, I am very troubled, so I have not updated the new version. How to set up the new version?

From FF90 browser crashes when split tabs for the second time every time I try.

It just opens tabs in separate windows and aligns them. My window manager can do that.

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。
