Adopt automatic tree structure for vertical tabs

[WadeK]

The new vertical tabs arrangement is an excellent step forward but with the current presentation based on a simple "flat" list of tabs the available display space runs out pretty quickly. I'd love to see a management / presentation approach similar to that used in "Tree Style Tabs" extension.

Thanks for submitting an idea to the Mozilla Connect community! Your idea is now open to votes (aka kudos) and comments.

I agree. I still have to use Tree Style Tabs (which works great). Hopefully the TST extension can be absorbed into Firefox as a native feature. It's one of the things which is unique to FF and makes FF so great.

Yes😀, tree-shaped organization is a superior replacement for grouping organization, and also provides convenience for closing all web pages that are only open-browsed once. Hopefully this is a built-in feature of FF instead of having to use plugins to achieve it.

I completely agree! The new vertical tabs are an awesome first step, thank you for making it happen.

I am a heavy user of Tree Style Tab Extensions, and it makes my tabs management fully organized with no effort; every link I click on a tab become children of the tab; this then serves as containers that I can expand and collapse at will, and get back to whenever without having other things mixed in to scroll through. This helps a lot with context switching, with no effort on my side to organize things.

Also agreed. It's cool that Mozilla integrated vertical tabs, but I forced to use tree style tab ext, cause of the comfortable tree structure. I also forced to use userchrome.css hacks to hide horizontal tabs. Hope that team will hear us🙂

Also agree. I used tree style tabs for years now, and removed it completely to try the new firefox native vertical tabs:

The "tree" is really missing for me... Here is the user story: The idea is to deep dive in a subject as a mind map approach: You start with a search, open the first relevant links in child tabs (automatic, or middle click). Then the new tabs can lead to new links when you read them that also opens as sub-childrens... And when you found out what you want, you move the relevant n-th child to the top level, then close your initial search (and it closes every children).

(edit) If you're looking at the option "always open links in tabs" (not exposed in settings menu), search for "intab" in the "about:config" page.

Agreed here too. I heavily use tree style tabs, and while I am pleased to finally see a native vertical tabs feature, I cannot yet transition from it. The tree structure is the best method to manage hundreds of tabs for heavy users.

It is awesome to see Firefox team implementing features based on our feedback, so hopefully they will hear us here!

An emphatic +1! Vertical tabs are the table stakes (save vertical screen real estate, more attractive, etc) but incorporating a tree-style view is where the magic happens.

Pirp nailed the user story, so I don't have much to add beyond: "Please implement this next!" or at least expose the ability for extension authors to create this functionality using the built in Firefox tabs.

TST is a must with plenty of functionalities and a large capabilities to adjust the behavior to your liking.
To me, TST should become a native part of Firefox
