I came back to firefox because of TST and Sidebery made sure I'll stick with firefox. It does everything I missed in TST and looks beautiful. Animations where kind of laggy for me but you can turn them off in settings, so problem solved. Awesome extension, love it <3

Absolutely amazing extension. So many options for customization..

I have been using vertical tabs extensions since they started making them. I think this is the best looking one and really customizable. Thank you.

The Perfect plugin!!! thank you

does everything piroor's tree style tab does (the core functions I used anyway) + it works with tab saver extensions without losing the tree hierarchy.

This should be a recommendation from Firefox

I recently move from Vivaldi and this is what I was looking for on Firefox. Best extension I've ever installed, configuration page is also extremely friendly and useful. I wish I can vote twice.

First addon I've bothered creating an account and writing a review for because it is just that danged good.

I installed this addon for tab management, but I discovered it has many other features that make it stellar. (See below)

3 tips for those starting out:
- Click on the gear icon to see the million customization options.
- Enable the bookmarks section so you can go back and forth between your tabs and bookmarks in one section
- Double click on empty space below your tabs to create a new tab

## UI / Aesthetics
- Muted, minimalist, great for those using Dark themes (although you can change most of the colors, I really like the defaults)

## UX
- You do have to do things in the app the way it wants you to.
- Might not be as use friendly as it should be. Perhaps the developer can do more to make the app user friendly. When I installed the app for the first time, it didnt even have proper screenshots on the firefox addon page. These new screenshots will help a lot with new user onboarding.

## Tab managment
- Does everything I would want with a tab manager:
-- Grouping tabs
-- Nested tabs
-- group open / close
-- Etc etc (everything else a tab manager type extension does)
- What's missing:
-- Session management (I have yet to investigate the snapshot feature
-- Ability to rename your tabs
-- Ability to look at the tabs from other windows (Although you can move tabs between windows using the right click menu, so this isn't a huge minus)

## Bonuses
- Containers are nice! I have to use them more, but its like a way to have "environments" for your browsing
- Developer seems to actively maintain this addon. Keep on chugging! I hope this addon gets the attention it deserves!

Review Edited: Awesome Addon, A worthy replacement of tree style tabs or Tab Group Manger etc etc. This one is full blown package with a lot of customization.

One request from developer to add tab search feature.

удобная штука спасибо.

awesome! simple, does everything i need and even more! Thank you!
