The number 1 reason why I use Firefox!

Es macht, was ich erwartet habe: ich kann Bookmarks hierarchisch sortieren.
Man kann immer etwas verbessern, ich gebe trotzdem 5 Sterne, weil ich es toll finde, wenn jemand etwas kostenlos programmiert.

Makes tabbing much easier and more user-friendly. Works exactly as stated. : )

Alors j'ai sous la main, tous mes onglets sans continuer à les chercher. Fantastique !

It's massively hyped by that one tik-toker. The downsides with using this is that it makes your browsing space smaller. In addition, if you're an impulsive person and accidentally close one browser, then you can wave ALL those tabs gone because your never going to get them back. Also it's a massive hassle to group tabs like this, but the upside is that its easy to keep control of tons of tabs.

Somewhat broken in firefox 100: the scrollbar doesn't display properly, making it difficult to expand/collapse trees without scrolling inadvertently. Also, the sidebar fairly often interprets single left-click as grab-and-drag.
