大量にタブを開いていると、ハングし、
Firefoxを再起動すると、一部タブが「新しいタブ」という名前に変わり、
以前開いていたページが開かれなくなるバグが何度も発生しました。

amazing! please keep it updated!

The best way to organize your tabs! Powerful yet lightweight on system resources.

Ty so much for rewriting this as a webextension!
Performance amazingly now <3

Adds a panel to the left. Background-tab links are opened as tab children. Has drag&drop to move tabs around. Specific display for pinned tabs. Does not hide the tab bar, so right now, I'm using it with full-screen navigation. One of the best tab management add-on, comparable to OneTab.

Makes better use of wide screens and shows more context.

Does what it says on the tin, no useless or overcushioned functions. Supports WE, and makes heavy-tab browsing much easier.

What's best is that NO other browser or extension can do this. Only TST can.

Very nice addon quite useful to manage tabs.

F1 is a nice shortcut ... but I prefer personaly F4 ... is there a way for me to change this somewhere ?

I had a look and found "F1" in the manifest.json ... (opened it with 7zip) ... but changing this just breaks the addon ...
So ... Please, tell me how to do this ...

Great addon but sometimes stops working. A restart will make it work again, but tabs and windows that I'd closed appear again. Real weird. Was fine until latest update, and I'm sure it will be fine again.

When working it's a useful addon and when devs have the ability to hide the top tab strip, we'll get a little vertical space back. Trees are great, too.

This is a great add-on. Gotta love those trees.

Because of that it's also much better than Tab Center Redux.

There is just a little thing missing. Make it so "unloaded" (not unread) tabs are visually distinguishable e.g. gray and italic font.
Maybe it's possible with some css in the advanced section but I couldn't figure out the tag for unloaded/pending tabs.
".tab.pending .label ..." doesn't work apparently

PS: Got it. It's "discarded". So if you want to give unloaded/pending/discarded tabs grey labels use this:
.tab.discarded .label {
color: grey !important;
}

5*

Great tree style tab addon. Maybe the best. One thing that i would changed: ability to close tab tree by middle mouse or by right click in first level of menu(would be much faster than now clicking from sub-menu). Thx for great addon! :-)

Now, in Fx 56.0.1 (at least 64 bit, Win10) the version Tree style tab 0.19.2017090601 is works (show in https://addons.mozilla.org/en/firefox/addon/tree-style-tab/versions/ ). But 2.x.x is "not compatible" yet.

But in Fx Developer Edition (57.0b11) Tree Style Tabs 2.0.8 is works (with new style of tabs by default).

Simply essential

I would love to try this add-on, but Firefox 56.0 refuses to install it.
Why does this add-on require version 57?

this plugin should be default in all browsers. Unfortunately it doesn't work well with last versions of Firefox :/ it's slow and doesn't look as good as before. But because it's been awesome until now it still deserves 5 stars. I just wish Firefox would put more effort to support this first class plugin.

If I can't use it in FF57, I will switch to Vivaldi. Have used FF since Phoenix 0.6 so this would be traumatic.

If chrome had this, I would be using that browser. I can't find any way to donate to you, do you have a donation page somewhere?

Very nice add-on. Once you're used to it, you do not want to go back.
