Super happy with this addon, it's a must have for me. It really boosts my productivity. Awesome job!

Great for someone like me who has a million tabs open at any given time.

I'd probably not use Firefox without this extension. Good quality, helpful developer, crazy customizability.

This is really awesome. One of the most useful addons. With pastebin it can be used as a notebook tree, similar to cherrytree

Excellent extension. Suggestion: a folder/workspace management allowing: (re)naming of folders, (re)assign a tab or a tab tree to a folder, activating or not a folder, assign a(many) folder(s) to a window, manage subfolders. I'm using TST for years and enjoy ;) Could help to specify this set of suggestions.

LOVE IT

This is hands down the best extension for Firefox. The end.

Grazie mille. Molto molto ben fatto!

Literally the best thing since sliced bread for all the people out there who routinely have 20+ tabs open.
