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!!!

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

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 :
https://medium.com/@Aenon/firefox-hide-native-tabs-and-titlebar-f0b00bdbb88b
- 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！

UPDATE 3-STARS: Frustrating that a core function to group selected tabs has been removed and now requires a separate extension to be installed.

ORIGINAL 5-STARS: Great extension, love that it can be extended by other extensions too.

Nice extension overall. There are a few minor tweaks I wish it had but nothing too big.

GANZ WICHTIG: Ich möchte die Tab-Leiste schmaler ziehen, aber das geht leider nicht. Ich würde es gerne so schmal ziehen, dass man nur die Symbole sieht und Lautsprecher.

A must have extension. 4-stars because of some features I would like to have:
* navigate to tab group instead of individual tabs with Ctrl + (number)
* renaming tab group
