very good

I love Tree Style Tab! Amazing add-on! I don't get it why the other browsers don't copy this feature.

One of the greatest extensions you can have. Edge pushes vertical tab bars as a really good feature, but what really makes a vertical tab design work so well is the branches and history of tabs shown with this extension.

This is one of those things that, once you have it, you wonder how you ever lived without it.

The simple ability to use tab groups and collapse when needed is an excellent feature. A must have!

Also (responding to another review), I am using macOS Monterey (Intel processor), and I do not experience memory leak issues. FWIW.

Awesome extension, I like how it uses the same theme as the one preset for Firefox
