branching tree indented view gets reset after restarting the browser

I have tried several similar Add-Ons, so I can assure you're grabbing the right stuff here.

The Add-Ons offers you a very good amount of thoroughly well-thought-of settings and features, highly customizable. I love that, there's no software with too much options for me.
Don't panic, you don't have to do anything before using this Add-On because it's - out of the box - GOOD
(and beautiful too)

I'm actually writing this review because I waive using it for a while to test out Mozillas first take of vertikal tabs. I find it way too simple. Like overly-simple, rather even unfinished. I'm so glad I can go back to Sidebery again so that I don't mind formulating a beautiful review for you in the middle of the night.

Peace

This extension just re-defined what a browser should look like

خیلی عالییییییییییییییییییییییییییییییییییییی

Deleted 800+ of my tabs

Excellent add-on. Reshaped my browsing experience!

I tend to keep a lot of tabs open, and have not gotten into containers or groups etc. This Add-on really helps me see all open tabs, the relationship between then, and easily move through them.

Sidebery isn't just a vertical tab extension; it's a comprehensive tab and workspace manager that fundamentally improves how you interact with your browser.

- Tame Tab Chaos: Replaces the cluttered horizontal tab bar with a clean, efficient vertical layout. Easily view, navigate, and manage even a large number of tabs.
- Powerful Organization: Features like tab nesting, grouping, and customizable Panels (workspaces) allow you to structure your browsing sessions logically by context (e.g., work, personal, research).
- Boost Productivity: Effortlessly switch between different tasks and sets of tabs using Panels. Finding the tab you need becomes significantly faster.
- Highly Customizable: While powerful out of the box, Sidebery offers deep customization options for appearance, behavior, and shortcuts to perfectly suit your workflow.
- Trustworthy & Open Source: Like the best browser tools, Sidebery is free, open-source, and actively maintained by its developer(s).

That's it! If you juggle multiple tabs or projects, Sidebery is a game-changer for bringing order and efficiency to your browsing. It’s an indispensable tool for power users and anyone looking to improve their workflow. Huge thanks to the developer(s) for creating and maintaining this excellent extension. Highly recommended for all Firefox users!

Excellent outil.
Plus besoin de voir les onglets. J'utilise d'ailleurs F11 la plupart du temps.L'écran est plus grand et plus lisible.
Tout est disponible dans la barre latérale à gauche, que l'on peut masquer.
On regroupe par container et dans chaque container on peut créer des groupes, une arborescence.
On peut sauvegarder aisément le snampshot, la disposition pour la sauvegarder ou la porter sur un autre Pc.
Il relâche automatiquement les onglets non utilisés, et ceux-ci restent accessibles mais en grisé.
Je l'utilise depuis peu, je ne reviendrais pas à simple tab group, celui-ci est plus ergonomique.

It's a broken mess.

Great for any fellow tab hoarders!
