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.

Helps a lot organzing tabs. Looks a bit dated but if you chose Proton theme in the settings it looks modern again

Tabs as tabs should be done. Frees up precious vertical screen space, especially in full-screen mode when the horizontal tabs disappear. Tweaking the appearance is a bit finnicky, but there are lots of options to play with.

This is an amazing extension that's legitimately changed my life. Thanks to this extension, I'm able to organize my class materials and streamline my experience on the web. I recommend using Auto Tab Discard to improve performance and modifying the userchrome to hide the top tab bar when using this extension.

Absolutely the best addon ever created for any browser !!! I can't live without it anymore.

Дуже зручне розширення! 5*
