Awesome!

Dear Piro,
after Install on Firefox 69.0.2 64 bit it was not possible to start TST. The F1 Key doesnt work and the mentioned TST-Button is not visible although the addon is activated...What to do? Deinstall? Please reconfigure your addon it seems to be very useful. Thank you

I have been using this extension for years and I must say it’s the best tab manager I know. There is nothing at the moment on Chrome which works nearly as well as Tree Style Tab does on Firefox (lack of native Sidebar maybe?). Use together in combination with the other addons that extend TST for the best experience and productivity boost!

This extension is one of the main reasons that keeps me on Firefox. If Firefox didn't have this, I honestly don't know which browser I'd be using ... but, in whatever case, I would be a sad little monkey! If you use more than 5 tabs, THIS is the way it should be!

Great extension in the very "limited" new Firefox. Thank you!!!

It works, so far, just as advertised and about as well as I had hoped. Also, in my opinion, this is the coolest add-on I could have asked for in terms of browser tab organization. It's really fun to use.

I had issues but realized my fixes we just in the settings. Really well thought out.

This add-on is amazing
but it used to be better

I have discovered my ability to drag tabs in tree style tab seems to be gone. Do I need to enable some permission?

Works perfectly (nonobstant les pertes de fonctions dues au changement du moteur de Firefox, ce qui est indépendant de la volonté de l'auteur) !

For those who would like to hide the native tab bar :

- toolkit.legacyUserProfileCustomizations.stylesheets to true
- create or edit the “userChrome.css” file and add the following :
#TabsToolbar {
visibility: collapse;
}

調べ物をする際にグループ化することで、簡単にタブを管理することもでき、大変満足しています

要望
・特定のツリーに対し、解放するという機能が欲しい
・「下／右側のタブをすべて閉じる」をコマンド化してほしい
・「下／右側のタブをすべて閉じる」をグループ内用のものが欲しい

これからも頑張ってください！

Great extension, love that it can be extended by other extensions too.
