Ironic to say on hackernews which shows massive whitespace in the margins-- and if I try to widen my tab sidebar it actually indents the margin rather than eating into it.
One can look across the computing space as a whole and see that, it is surely not the case that we're "maximizing screen space".
You think Hacker News’ design is new? It’s looked exactly the same since I started using it over a decade ago.
Totally agree. But this does not take away from his point that maximizing screen space is the motivation in Firefox. In fact, all you have done is demonstrate why they are driven to do so.
