Tabs on the side; Containers; Bookmarks; So feature rich! I've removed the default tab bar and used this add-on to replace it completely.

The BEST tab manager, I always loved TST but it was lacking some features which I needed like tab grouping. I discovered this recently and it is extremely customizable even suspends tabs automatically. The perfect tab manager I've been looking for. Thanks for the developer for creating this extension. Will never leave Firefox because of extensions like TST and Sideberry alone.

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!
