Almost everything nowadays is designed with mobile-first in mind approach - whether it's a smartphone or tablet, or desktop software. That throw all semantics out of the window - look what happen to e.g. Gnome over the years. What's worse I'd say, is that the lack of clear differentiation between types of interface elements made easier to hide options within GUI under various dark patterns (active element vs static information etc.) - whenever its required to do so.
As for Firefox GUI changes: Mozilla ask their users for feedback many times and the feedback was given - often strongly criticizing the upcoming changes but they ignored it and introduced changes anyway. I did submitted mine when they were about to rollout Australis but I didn't bother myself to say anything when Proton was about to be introduced because I knew that the corporate facet of Mozilla doesn't care and they'll do whatever they like.
