I have no idea why do people say that this extension is better then Tree Style Tabs.

TST allows CSS customization and way much more comfortable for me to use then Sideberry.

I tried SB 3+ times and each time I remove the extension to come back to TST.

Sorry devs, but your extension is so confusing to setup!

P.S. It's April 10, 2024, Wednesday and I did found out how to setup your extension. Looks like it is indeed better then TST :-)

I've been looking for this for a long time.

Works somewhat well. Close to Edge sidebar as you can get with Firefox.

Fantastic extension, of which I use probably 20% of the feature set. Right click to close a tree is especially valuable, as is moving a tree to a bookmark folder.

Thank you to the developers!

Significantly better than Tree Style Tab.

This is what I've been looking for, the equivalent of Profiles on Safari. Where can I donate?

This is probably the greatest plugin I have ever used on ff. It completely changed how I use my browser, in a positive way, of course.
Great work !

This extension is the reason I use Firefox as my main browser rather than Chrome or Edge. It is got so many options and settings to customize to your needs that it is invaluable to the tab hoarder.

Useful to use in combination with Auto Tab Discard Extension to prevent many tabs slowing down your machine.

Very thoughtful add that makes my job much easier
