Très bien, très pratique, mais l'installation provoque un comportement inattendu dans les autres fenêtres de Firefox dont le panneau latéral n'est pourtant pas réglé sur Tree Style Tab (sur marques pages, par exemple) : les nouveaux onglets s'ouvrent alors dans n'importe quelle position, et non pas à côté de l'onglet qui en a directement commandé l'ouverture. Une solution ???
Si je désactive temporairement Tree Style Tab, le comportement d'ouverture des nouveaux onglets redevient normal !

sangat membantu BINTANG 10!!

It only adds a second tab bar down the side, but you still can't get rid of the one across the top, so more space is wasted without increasing the depth of the useful space. You to think either Chrome or Firefox programmers would realize there's no need for a tab section at all if you only have one URL open.

Nice, although a bit slow every time when it's opened.
A live search/filter on top would be great (getting focus when side bar is opened)

One of my top 3 favorite add-ons for all of Firefox!

I HAVE ONE FEATURE REQUEST PLEASE!

Please add re-naming tabs and allow me to turn the feature on from the Context Menu or Tree Behavior section.

Pleaseeee!

Been using this extension for years and it is amazing. Wasn't sure where else to report this but recently the scroll bar has disappeared making it difficult to navigate.

Works great, just wasn't for me and created a lot of lag.

I've been using this extension at work for over a year now. It is perfect for when you need to work in many tabs at once. But for my personal computer I don't find it necessary, and prefer to use classic horizontal tabs.

Game-changing add-on! This is definitely my favorite extension.

On it's own it's an incredible add-on, however if you take the further extensions into account it turns it into a serious 10/10.

The extensions that you can install, especially the core extensions maintained by piro themselves, makes it the main reason why I even use Firefox at all.

Using the multiple tabs handler, More Tree Commands, and the bookmark subpanel, makes researching topics a breeze. You don't have to struggle with the browser and can get on with your work.
