> Firefox always felt slower to me
Since Google has proven willing to stoop to bad behavior to lend Chromium the impression of superior performance[0] I don't consider subjective performance to be a meaningful benchmark.
As metrics go, I am more concerned with "demonstrable respect for user-agency", a competition in which a browser from the world's largest advertising conglomerate is forbidden entry.
