I've been using TST for ages now. I'm glad to see it's made the leap to Firefox 57, and it works really well here. Highly recommended!

An essential extension for those who open a lot of tabs. It is especially useful for grouping tabs from various sites.

It would really be helpful if it were possible to disable the tabs at the top of the page.

Well designed, simple, and easy to use. Beautifully integrated into the builtin Sidebars. Tabs are automatically arranged in a hierarchical structure and you can fold and unfold a parent item. I've only started using this minutes ago, but I already love this addon!

great, but now i have tree tab, the orignal tab bar is not nececery now, how can i make it disapear?

Very useful, clean and light weight. Also, an excellent port to the new firefox infrastructure.

Great extension - allows for really intuitive organization of tabs.

Wonderful!
There used to be a "Search Tabs" feature. Is it possible to bring it back?

The best tree-tabs add-on. Long time user (~5 years) and I like the migration to the web-ext. The only ask for firefox developers is to put an API to hide the old tabs bar so that it can be used by add-ons like TST. Currently I am hiding the tab-bar from the userChrome.css.

Shameless plug: I have written the load-progress-bar add-on to give me a little better idea about the page load progress that I am missing in the new FF57 and I find useful in combination with TST

One of the main reasons I choose Firefox - this makes it easy to maintain separate workspaces for different projects, and to keep track of a lot of tabs. Incredibly useful

10/10 !

to hide the usual tabs, and to hide title bar of TreeStylTab

[your firefox profil folder] /chrome/userChrome.css
--------------------------------------------------------------------
@namespace url("http://www.mozilla.org/keymaster/gatekeeper/there.is.only.xul");

#tabbrowser-tabs { visibility: collapse !important; }

#sidebar-header {
display: none;
}

Great when juggling multiple tabs. A must have! Easy to use without any issue at all. 5* from a satisfied customer.

This extension has changed my life. My work can involve juggling many web pages, whether I'm maintaining issues in JIRA, Writing pages in Confluence, filling in timesheets, or any number of other things. So many mistakes used to happen when I had 3 copies of the same page open at the same time and editing content in 2 of them at once without noticing. But no more! All my pages are now organised in a way that actually mirrors the way I'm working. This is a browser extension that makes me smile! :-)

This is one of the extensions I can't browse without after trying it for about five minutes!

It's just perfect for maniacs like me who tend to have at least a dozen tabs open at any time. Especially at work where I like to have the complete trail of websites visited while researching the latest technical problem(s) available and organized.

Very useful: With this extension I get a better overview of my tabs. The only thing I miss is "Custom Tab Groups". For example: Work, Personal, Programming, Todo, etc.

Thanks for this addon!
I really like the native tab bar, but I also like how Tree Style Tab groups related tabs together. So I created an addon based on this addon that colors the native firefox tab bar based on the group the tabs are in.

First: If you think the add-on doesn't work, press F1 or click the "Tree Style Tab" button that appears. The options page tells you this, but we all know people are too impatient to read the manual and expect everything to be done for them instantly.

Due to current limitations with WebExtensions (in Firefox 57.0.2), this add-on can't remove tabs from the top of the screen, so the user has to do this themselves by modifying their userChrome.css file. There is a post on the Firefox subreddit detailing how to do this, but I would like to see this guide included or referenced in the options page until such functionality can be added to the WebExtensions API: https://www.reddit.com/r/firefox/comments/736cji/how_to_hide_native_tabs_in_firefox_57_tree_style/

Caveats aside, Tree Style Tab is still an exceptional organizational tool for anyone who has a habit of opening new tabs for everything. With the tree organization, you always know which tab opened from or is related to which other tab, and the options for how you want the tabs to behave are extensive. The only faults I can find have to do with limitations of the new add-on engine, so I can't think of any reason to deduct stars. Great add-on, essential to how I navigate the web.
