Hey Brave Nightly community,
I’m reaching out about the experimental vertical tabs (tree tabs style) feature. I’m noticing that tabs are grouped by domain, but they’re not really working like a true tree structure.
Is this the expected behavior or is there a bug? The tabs look kind of weird - grouped but without the classic hierarchical tree tab layout.
Has anyone else noticed this, or do I have something configured wrong?
Cheers,
Can you share a screenshot of exactly how the tabs are displaying on your end?
Oh I see – this is just a placeholder for now. We haven’t actually implemented the feature yet:

### Description
Hello Brave Team.
Many Firefox refugees su… ch as myself are looking for a way to replace Firefox permanently, as [we have lost faith in Mozilla's leadership.](https://x.com/BrendanEich/status/1895231159040385198)
However, Brave still does not present a perfect escape.
There is one feature in particular that I'm searching for: **real Tree Style Tabs**.
[Tree Style Tabs](https://piro.sakura.ne.jp/xul/_treestyletab.html.en) is likely one of the inspirations for the Brave Tree Tabs feature, as it was one of the first implementations of its kind (if not the very first). It was created by the genius known as @piroor.
To this day, this extension has, in my opinion, yet to be beat in terms of its achievements and usefulness.
It is one of the main things holding me back from ditching Firefox completely.
Please consider hiring @piroor. And barring that, please consider incorporating some of his brilliant ideas into your own implementation. 🙏
Notice that unlike Brave Tree Tabs, TST:
- Is hierarchical
- Is incredibly information dense. I have sometimes hundreds or thousands of tabs open.
- Uses totally different styling on different tabs to show tabs that have yet to be visited, or yet to be loaded.
- Is highly customizable
- Can collapse sections of tabs
- Is capable of handling and integrating with container tabs
- Also [works well with other extensions](https://github.com/piroor/treestyletab/wiki/Helper-addons-extending-functionality-of-TST), so that you can really take your tab experience to the next level beyond even TST, and have different groups of TSTs using extensions like [Simple Tab Groups](https://github.com/drive4ik/simple-tab-groups) and act on multiple tabs at once using [Multiple Tab Handler](https://addons.mozilla.org/firefox/addon/multiple-tab-handler/)
