Highly useful addon. It's smart and practical, and provides you with the tools to use it smoothly.

I've used it for a good long time now, and I haven't had any issues at all with it.

It doesn't take up a lot of screen space, which is a boon in my book. However, that means it's not an in-your-face, shiny and fluffy kind of addon. It's a tool. It does what it says on the tin, does it well, and lets you get on with your browsing.

Einfach Praktisch

Really enjoying the groups and it's helping with alot of things I'm involved in
Could you include an option to open new tabs in a chosen folder?

Mein meist-benutztes Add-on. Käme ohne es bei hunderten von Tabs gar nicht mehr aus. Funktioniert bestens in Verbindung mit multi tabs rows von github. - My most used add-on. Can't work with firefox without it. Additionally I use multi tabs rows from github. Many thanks to the developer for the brilliant work!

This extension + a "TabUnloader" extension made it perfect for me to manage and order as many tabs as I want with the lower resources usage. It's awesome

Honestly one of the most useful extensions, found it by luck xd

Gorgeous, easy to use and beautiful!

i like panorama

best firefox addon for me

This single extension is the only reason I am not switching to a chromium based browser. True life saver. Right now I have about 830 open tabs in 11 different groups and, thanks to STG, zero trouble handling them. I specially love the hiding other groups idea.
