That's... not accurate at all. Firefox was extremely popular at one point, and completely ate the lunch of everything else out there. (And then Google used anticompetitive practices to squash it, but that came later.)
Not exactly. Apple happened.
Every "web designer" had to work on a macbook to be different like every one else. And firefox had dismal performances on those macbooks so said designers turned to the only browser with good tools and good enough performances: Chrome.
Next time you're told "performances don't matter", remember how it can be a differentiating feature and could cost you your market share.
Sorry? Why? I must’ve missed that memo :)
To be honest it's still better (at least if you ignore the manifest V3 nonsense).
