One of the best things that happened to FireFox (IMO).
There are few quirks but I circumvented them by disabling cache, drag of tree tabs to another window and most important by shutting down TST sidebar before closing browser (that last part prevents from "mangling" order of tabs inside tree at launch).
Thanks to that I can safely manage 2000+ tabs on small Atom based CPU.

P.S. Please remember that one can hide FireFox native tab bar at top by editing profile file userChrome.css and adding lines:

/* to hide the native tabs */
#TabsToolbar {
visibility: collapse;
}

/* to hide the sidebar header */
#sidebar-header {
visibility: collapse;
}

这个插件是让我选择火狐的唯一原因

Have used this for a long time now and have had a near faultless experience.

The one time I did have an issue, I raised it on GitHub and the developer had responded and fixed it in no time at all.

Great extension for people that like/need to use a large number of tabs while still making it easy to navigate between them.

This morning I lost the feature where I open a group of bookmarked tabs and they all opened in one tree. How do I get it back?

Tree Style Tab is life saver if you open lots of tabs (who doesn't 🤷‍♂️)

It groups tabs based on how from where you opened it, and I love it

Thank you for building it

非常好用

This is beyond useful, especially with the userchrome.css rules that people tend to recommend at the same time as it. This changes the whole tab-management game, why isn't this built in to everything by now?

So useful. Thanks

If there is one extension you should consider, this is it. This is the main reason I use Firefox. I won't consider any other browser because of TST. No other browser has anything this fabulous. I started using the basics of TST as soon as I installed it. Over time, I began customizing it by adding more and more of its functions and making it even better.
