This is an amazing extension that's legitimately changed my life. Thanks to this extension, I'm able to organize my class materials and streamline my experience on the web. I recommend using Auto Tab Discard to improve performance and modifying the userchrome to hide the top tab bar when using this extension.

Absolutely the best addon ever created for any browser !!! I can't live without it anymore.

Дуже зручне розширення! 5*

It works flawlessly for what its supposed to do - I'd love for it to hide the classic horizontal tabs bar when active.. but thats extremely hacky even for local users let alone addon. 5/5. Just get it.

Absolute must have for anyone who is working or living in the browser (i.e. has more than 10 tabs open) 👍🏻👍🏻

Anyone else having this issue in Tree style tab? I can't see the text. So I wanted to edit the Tree-style-tab config. And... this happened. So I changed it to white theme thinking that was it... no. I disabled dark reader- nada. I disabled my CSS stuff, and that wasn't it. I even reinstalled. Nothing

Tree Style Tab de Piro (piro_or)

It's a must have for me, BUT there is a bug when FF 68.9.0esr crashes:
I had a structure with about 50 tabs. I closed this window, left an other open. The closed window was automatically saved in "Tab Session Manager". Shortly later my Browser crashed. I thought no problem I have saved my important window and structure.
. But NO, after FF restart there are no chronicles within FF and after restore from "Tab Session Manager" the structure was lost.
-> This loss never happens when I closed and restarted FF.

My questions:
-How do I get back my structure ? or
-What must I do that in this situation my structure is automatically restored ?

Hopefully you are able to help !?! (running OS is Windows 8)

NOW I found a solution for me. Perhaps you will correct this once:
I found out that a restore from "TabSessionManager" is mirroring the tab-order.
So when Firefox is crashing and I really have to use a restore from "TabSessionManager", I save again the restored tabs and restore it again.
-> A double-mirroring will bring it in correct order and "TrueStyleTab" brings back my lost style.

Conclusion: I think the fault is in "TabSessionManager" not in "TrueStyleTab"

Extensão excelente para quem, como eu, sai abrindo várias abas a partir de uma. Permite não só fechar todas de uma vez como também organizá-las de forma simples e rápida.
