Great, must-have addon, and first reason to using FF for me.
- Tst toggle hotkey change option is needed. f1 by default, srsly?
- Tab context menu needs custiomization too:
-- missed some important options from tabs (Send to other device, etc);
-- ... but its overloaded with items that I would like to disable

Also some occasional errors: seens descend background tab sometimes opens in wrong tree; multiple tabs closing sometimes breaks on halfway

Awesome!

perfect!

Just amazingly useful!

Love the grouping feature and that I can close individual tabs with their own [x] button without having to first navigate to them.

Some ideas:
- Visually maybe it would be best to show each tab's [x] button on hover though
- Should be able to drag left to ungroup (unindent) one level and drag right to group under the previous (above) item
- Also, it would be really if a filter box was on the top to select which tabs to show (filter titles using typed substring). Indentations should be remembered (that is have invisible parents if those are filtered out). If hard to implement, it could at least highlight found items or gray out items not found. Could also have that as option and could have Previous/Next button to select next tab that matches the filter

BUG report: 3.9.21 broken, reverted to 3.9.19 and that fixed it.
When it works, it works. absolutely necessary.

Tab Tree was better. Too bad about ff>55

Been using this add-on for ages, keep up the amazing work!

I really love this extension because it makes organising my tabs so much easier and logical. One issue though is that when I restore tab after a crash, I lose all the trees. I have to manually make the trees again which can be pretty annoying. It would be fantastic if you could fix that

Makes your tabs more like a folder list. You can collapse individual branches of the tree and really see a whole lot of tab roots all at once. This is the way all tabs should be done in every browser!

シンプルで使いやすいです

【Bug report】After the last update in March. The tree bar stays in loading status forever, cant see any tabs but a loading icon.
But if I disable and then enable this addon, everything goes well.
It happens everytime when I open firefox.

Number 1 add-on of any add-on that has ever existed:
A+ | 10/10 |

Must have. Cannot use a browser without it. No other add-on has the same feature. Thanks a lot!

The reason why I am still using firefox and love it very much. This is must have addon, that makes life easier and more organized.

作ってみてわかったけど、
かなり細かいところまで、お手製で作りこまれている。すごい。

Great extension!
The only thing that could be improved is a default smaller tab height like before the WebExtensions version. But it can be changed with a code snippet found on the extension wiki.
