That my view is narrow
Yes. Your view is narrow. You do not care about the technical details and just label Firefox as “bad/broken” because you do not know how to work with it. That is a pretty narrow view. You do not care about the idealogical reasons that people bring up in here either.
and that developers somehow can’t have narrow views.
I am expecting a person that is talented enough to be a developer to not have narrow views.
