This is the best way I know to manage my tabs. It is absolutely excellent with lots of features.

I can't imagine a life without this addon. Thank you so much Piro.

I liked the functionality of this extension a lot, but it slowed my Firefox to a crawl... like 6-8 seconds for a click to register. I had about 20 other addons, so there may have been conflicts. I decided to uninstall it for now and switched to Tab Center Redux.

I like the concept and the customisability. What does not work well is pinned tabs. When Firefox is closed and reopened the pinned tab is gone.

Fantastic! Thanks!

Great extension for any multi-tasker, end of story.

This extension is absolutely essential for doing research, looking through programming references, and general reading and browsing. I don't remember what I used to do without it!

If you open lots of tabs, then TST is a must! No other browser or add-on can manage your tabs as easily or efficiently. This app is the reason I use Firefox over any other web browser ^_^

This extension is the USP of Firefox and the reason I still use this Browser! Thank you so much Piro (piro_or)...

I wanted to like the Opera group tabs extension is now absolutely useless!

Tree Style Tab is my first reason after security and privacy to use Firefox. I really can't imagine browsing without such an extension. Great job, Piro!

Great addon, but tabs got scrambled once in a while, which completely messes everything up. It's not happening very often, but when it happens, you need to spend a lot of time to fix it.
