The "new child tab" does'nt work, even if correctly selected in the pref
There is no possibility to middle cliq and have the possibility to create a new child tab...

WOuld very great if TTS interact with multi-account containe, so that a new child tab has the same contaner as its parent

Bigthanks !

Usable add-on.
I am missing the feature to hide tabs automatically or at least using some shortcut for example F4.

Seems to be a reasonable substitute for the XUL-version. An absolutely essental addon for firefox!
But I like to report a bug. When I click on a tab and drag it to another window, the tab disappears from the source window (as expected), but does not reappear in the destination window. First you believe that it has been erased, but turning off the sidebar by clicking the show menu, and the turning it on again makes the moved tab magically reappear.
I hope you can fix this soon, since it is very confusing..

Tree style add-on really works for me to reduce the hanging of the browser when opened so many links and also tabs can be shown in front. Thanks..

The previous version had exactly what I was searching for, meaning the ability to group (and collapse) tabs together while remaining at the top like the default tabs.

I am using half-width windows all the time, so the side bars take way too much space for me, so sadly I had to disable it once firefox forced its update and new plugin versions on me, but I am still hopeful that one day it will give us that functionnality back.

This extension would be perfect if the author could hide the children tabs from the top bar tab so you would have only the parents on the top and the children on the left, a superlative UX tweaks!

I'm very glad Piro had a revised version of Tree Style Tab for the latest major revision of Firefox. The user interface has changed, and functionality is somewhat less, but the core features remain present.

Полезное приложение, хоть что-то, что позволяет получить нормальные вкладки а не эти скукоженные сверху, а можно добавить авто группировку вкладок чтобы 1 нижние адресу группировались под верхним? по типу

Thank goodness you have updated for Ff 57. It was showing as "legacy" and I was dreading the loss of TST. But it isn't as good (yet): The cross for closing a tab is on the left, even when the tree is on the right of the browser - I always have it on the right. And the Ff tabs show along the top as well as TST's tree at the side! I know it's early days but I hope you'll fix these two things very soon.

Also, thank you for the instructions for converting session information manually - but I'm fairly tech savvy and didn't find it straightforward. Many users won't know how to start "command prompt", how to find the profile directory, where to look for about:support. I corrected/removed a typo in the code you gave (intelligent guessing based on distant memories of DOS - I decided to risk it! I'm not a programmer) - but not everyone will know to copy and paste that, nor to paste each line one at a time, nor to remove the C:...> from each line. These things aren't obvious if you don't already know. Then I looked at the addon options, after converting the session info because that came up first of all, and saw another way of converting (not manually) but no advice how to do it; maybe that would have been more sensible, I can't tell.

Some user feedback for you, the "non-techy" point of view. :) Overall though, very very glad to have Tree Style Tabs as I'd never want to live without it. :)

UPDATE 18th Nov '17: Just been surprised by a tab opening that told me why the top tab bar can't be hidden. I'm not techy enough to risk the workaround, I have no experience customising CSS. I understand it's the fault of Firefox and can wait... hoping it isn't too long a wait! But in the meantime: (1) Can we have a context menu link to settings, instead of having to open extensions manager, please? and (2) the "Allow to create bookmarks" checkbox (under "Bookmark this tree" in the context menu options) won't allow me to select it, it just blinks and stays unchecked. Oh, and (3) the option for fixing the width back in the context menu - if that's even possible, now we're forced into using the sidebar instead of "real" tabs-at-the-side?

I really don't like any other browsers, I periodically try them all again (whenever I get fed up with Firefox!) - especially since Ff stopped supporting Java - but I don't know if I can cope without Tree Style Tab. Let's hope the voice of the masses is heard, so many people feel trapped and cheated by this unwanted update to 57. Looking foward to whatever you can do to make TST great again. :)

Its my favourite add-on. One star less because the 57 version does not hide the standard tabs.

Great thanks!!!

Have just started using this with FF57, as the "list tabs" drop down that I'm familiar with from v. 56 and earlier seems to have gone AWOL. Tree Style Tab addon meets this need nicely, even if a bit more cumbersome than the old button used to be.

On the plus side, it has more features that I'm guessing I will grow into: it took me a moment to find the "expand/collapse all" toggle, for example, but it's there! The themes are decent, but I would prefer one that didn't differentiate the "sidebar background" from the "tab background" -- perhaps there is one already, though. Also, it would be nice to have an option with more compressed presentation.

On the whole, though, quite a valuable addon, and kudos to the developer for having this ready to run in the new world of Firefox Quantum.

Must have extension! I can not work without it. However, last days, very annoying bug. New tabs are not visible in tree sometimes. They are only in standart horizontal title bar.

It works! And it's a tree! And there are many and sensible config options! And it integrates with containers!! Wooohooo!!!

You have to manually disable the horizontal tabbar at this moment. This is a limitation of the webextension api, not something this extension can currently do something about. But once that's possible, it'll get the final star ;-)

Love the extension. Please find a way to remove the tab bar at the top!

Works well. Just need the top bar of tabs to be hidden.

just got it

Как скрыть вкладки сверху?

Latest update today with the desire for new permissions has caused the addon to fail. Before this I am grateful it was ported over to the new design. This is the main reason I use FF. Please help fix this issue.

Update, just clicked to add again to Firefox and it fixed it. Odd but ieast it is working again.

Please justify in the description why the permission to access data from websites is required. It could deter people from using your fantastic extension, which would be a shame.

For those interested, justification for website data access permission is given here : https://github.com/piroor/treestyletab/issues/1536#issuecomment-344541809

my only issue (after finding the work abouts for the top bar to go away...is making the tabs "thinner". the one bit of code that was here scrunched it all up and i couldn't make hide nor hair out of my tabs. I suppose screwing around with css and figuring it out is going to be something i'm going to have to do...if only to figure out which tag needs changed to get them thinner without everything running together.
