I have the same workflow. Usually, I never have more than maybe three tabs open, but when I’m debugging something… oh god. Easily 15 or 20.

I also bookmark extensively, and actually have my address bar set up to only give me suggestions from my bookmarks. Additionally, I use a tiling window manager, which makes managing windows and tabs very easy. I really don’t have a use for tab groups, but, who knows, maybe I’ll learn to use them someday.
