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.

I have firefox 57 and the add on doesn't work

Suggest: if it's not possible to auto-hide the TreeStyleTab-Sidebar, would be great showing the tree in a new window, like the Bookmarks Manager window.

Nice integration in FF57 !

Can you add a configurable keyboard shortcut so we can fast switch between bookmarks (CTRL-B) and Tree Style Tab (CTRL-something) ?

Is there any way to save a Tree Style Tab session and get the tree as identical when loading it ? When I use Tab Session Manager the tree is lost :(

Thanks !

Amazingly useful addon. Makes tab management so much easier that I couldn't use a browser without it.

First time user. Looks good and seems to work fine with the Containers extension. Needs a bit more polish which I'm sure will come as webextensions matures on Firefox. Thanks for the hard work! :)

Tree Style Tab was a major reason I kept coming back to Firefox after trying to switch to Chrome. Now that Quantum has sped up Firefox, I'm so glad there's a WebExtensions version of TST and it works pretty much as well at the old one, but less laggy!

just works

とても便利に使えていますが、大量にタブを抱えていると落ちて復旧するときにツリー構造が破壊されることがある感じがします。
上のほうにあったタブ群が下に来たり、子タブがぶら下がってるタブがただのフォルダのようになって内容が復帰しなかったり、その子タブの一番下のタブを閉じるとなんか反応があったり。
Tab Session Managerとの併用なのでどちらの問題なのかはよくわかりません。

I'm so happy to see this has migrated to quantum. Huge fan and glad to see it will continue!!
