À propos de cette extension

Les nouveaux onglets ouverts depuis l’onglet courant sont automatiquement organisés comme « enfants » de celui-ci.
De telles « branches » peuvent facilement être repliées (cachées) en cliquant sur le triangle vers le bas apparaissant sur un onglet « parent », vous n’avez donc plus à subir la présence de trop d’onglets.
Si vous le souhaitez, vous pouvez restructurer l’arbre avec le glisser-déposer.

Un tel arbre d’onglet se comporte comme un historique de navigation visuel pour vous.
- Par exemple, si vous voyez une liste de résultats de recherche sur un sujet, vous ouvrirez chaque lien de résultat dans un nouvel onglet enfant.
- Pour plus de détails vous allez aussi ouvrir plus de descendants à partir d’eux.
- Vous creuserez de plus en plus sans perdre votre fil de navigation — si vous souhaitez revenir au résultat de recherche initial, vous avez juste à aller à l’onglet « racine ».
De plus, vous pouvez juste considérer les arbres d’onglets comme un « groupe d’onglets » à propos d’un même sujet.

Bref, cette extension fournit juste une fonctionnalité d’« arbre » non-coloré.
Profitez-en bien !

Astuces :

La touche « F1 » active ou désactivé le panneau de TST
Le bouton « Tree Style Tab » de la barre d’outils peut aussi activer/désactiver le panneau. Si ça ne vous est pas nécessaire, vous pouvez l’enlever de la barre d’outils.

Permissions:

This extension needs following permissions to work as expected:

Required:
- Access browser tabs: to list both active and non-active tabs in the UI.
- Access recently closed tabs (access to the session information): to save tree information of tabs (structure, collapsed/expanded state, etc.) to tabs' session information and ask to Firefox to manage them as bundled.
- Display notifications to you: to present information and navigate users without blocking.
Optional:
- Read and modify bookmarks: to simulate bookmark related commands in the tab context menu. / to detect tabs whether they were opened from bookmarks or not.
- Access your data for all websites (run scripts on webpages): to detect the Ctrl key is pressed/released and prevent needless expansion of collapsed trees while tab switching with Ctrl-Tab/Ctrl-Shift-Tab.
- Hide and show browser tabs: just for automated tests, not required on regular use.

Helper addons:

TST is aimed to keep it simple and work together with other addons as possible as it can.)
