When it works it's cool, but sometimes it just keeps loading and nothing happens! Now I have 3 tabs open and its been 25 minutes, still it is showing the loading animation, 25 minutes to load 3 tabs is not right. Very nice add-on but very buggy. The only solution is to close the tree style tab sidebar and then again click "show sidebars". Then it works perfectly. Hope its updated soon.

非常不错的主意！！！！当标签页多起来时，看着原生的标签管理 你会忘了你到底打开了些什么，一团糟。现在一切都好起来了。

This extension is the main reason I use Firefox.

One request: I wish settings/custom CSS would use Firefox Sync.

I have been using it since a long time ago.
However, we frequently lose tab positions in various situations, such as when restarting or restoring with a session manager.
Moreover, I also forget the hierarchy.
This is fatal.

This extension bugs out a lot, forgetting the positions or tabs between plugin crashes and even between F1 sidebar toggle presses. I LOVE it when it works, but I HATE it when it doesn't, as it takes at least 5 minutes to fix the mess it creates when it breaks. (All the tabs are randomly ordered, parents forgotten, some tabs are even missing from the tree altogether and exist as "ghost" tabs between ones actually in the tree!)

This is an invaluable extension, seriously! It's one of my biggest practical reasons for using Firefox. However I have noticed that the tab context menu doesn't always show options that should be added by other extensions, which is quite annoying. Oh well. This is a fantastic extension still and I'm grateful it's being updated :D

This extension is one of the reason I keep using Firefox. Makes it easy to use hundreds of tabs. Has all the functions I need and is still in very active development.

Great for organizing tabs. Now this extension and the ones like session managers and tab groups (Panorama) need to integrate with it.

Brilliant idea, poor solution. Unstable a buggy in all versions.

A necessary extension to Firefox. The main reason I use Firefox is for vertical tabs, and this works very very well.

I had a recent problem with TST not initializing, but removing and re-adding the extension fix me right up.

I can finally organize links in a sane way. Bookmarks are too permanent, while just leaving a pile of tabs is too unstructured. This works.

This is great.. when it works. When it breaks Tab indents, it's impossible to fix.

Most important basic function is missing!
-indenting/outdenting tabs can only be done with drag/drop, and very inconsistant.
-when parent tab becomes independent you need to drag and drop each and every one below it back.
-NEED simple keyboard shorcut or option menu or UI shortcut (left/right arrow) to indent/outdent.





Stuff to fix
--indent and outdent current tab: need keyboard shortcut or context menu (drag and dropping is a bit too hit/miss)
-new tabs/"insert to the top of the tree, as the first child" doesn't work with Ctrl+T
-keyboard shortcuts are not modifiable
-some recovery issues with Tab Session Manager.
-but a bit unstable and Laggy after about 80+ tabs
nice to have!
-backup / restore settings?

I've been having some issues w/ TreeStyleTab since update 59. Before 59, i could do the chrome.css hide trick suggested here: https://superuser.com/questions/1261660/firefox-quantum-ver-57-how-can-i-hide-the-horizontal-tab-bar-with-treesty and everything worked fine.
Now w/ 59, I don't see the text in tree style tab view and can't access any right-click menu options.
I use FIrefox on Windows 10 x64 - rev 1709.
This is disappointing since tree-style is the reason I use FF.
When will Tree Style Tab be updated to resolve these graphical anomalies?

Very helpful with 100+ tabs across multiple windows as it opens a sidebar which is specific to each.

Put it together with Auto Tab Discard and boom!

This has changed my life. I am able to stay on top of tabs much better when I can see them this way. After Firefo Quantum came out, my preferred tree-style tabs add-on no longer worked, and I thought I was banished to an endless sea of horizontal tabs forever...thanks for your work on this!

Lovely extension. I expect to see more improvements in the future. Would be nice if it used ideas from https://chrome.google.com/webstore/detail/quick-tabs/jnjfeinjfmenlddahdjdmgpbokiacbbb?hl=en

An essential extension if you have about 200 tabs open, like me :-)
Thank you so much for your hard work!
