I’ve been using Fenix (“Firefox Preview” for now) for quite a while and it’s promising but I actually liked some of the features of earlier iterations of it much better. Collections, however, are the absolute standout of this browser. It is so great to have bundles of tabs at the bottom of the home screen saved and ready to go without having to mess with a favorites bar, organized or not. Outside of normal testing, I find myself using this browser specifically because of the “Open Tabs” area (and now the “Collections” area) because it makes it so easy to pick up work on continuing projects. Will it replace my primary browser (Tor)? Absolutely not. But it is good for what it does.
