Firefox profiles suck. Their UX is so bad. Containers are better but still have their issues. I use Containerise plus Cookie AutoDelete plus Temporary Containers to give me what is effectively per-tab private browsing. The major downside is that I have to copy containers.json (which enumerates all of the dedicated containers I have defined, e.g., for Facebook), my Containerise rules (which automatically puts certain web sites into specific containers), and my Cookie AutoDelete config (which says which cookies to delete and when) among browsers manually. I wish more things supported Firefox's sync feature. I ended up adding them to my dotfiles, so it isn't too painful, but it definitely isn't grandparent friendly.
That's what these changes aim to fix. You're getting a Chromium-like profile switcher/manager.
> Containers are better
Containers are very good... for container stuff. Profiles allow us to have different bookmarks, settings, extensions, themes, etc. Different tools for different jobs. I use both!
If you look at about:profiles and compare it to the new UI or to what Chromium has offered for years, then I think you'll understand that the new UI is much better for the average user. There are also improvements for operating systems like macOS, where profiles always worked, but switching between them wasn't exactly a nice experience.
You can still use the old profile manager. At the pace Mozilla moves, it will be there for years.
The old UI != about:profiles. I never knew about:profiles even existed for a long time, why I was already happy using the profiles UI for years. I mean the profiles UI, that pops up at startup.

No I think this looks way worse, than the native UI, they have had for decades and hope they don't remove the old UI, so it startup doesn't become slower and more annoying.
