Small thing, but the footnote references render incorrectly for me: they're rendered as normal-sized text, rather than small superscript. Separately: what does an "X" on "zero telemetry by default" mean for Firefox? My understanding/distant memory is that Firefox asks users to enable developer metrics, but that it's (1) opt in, and (2) distinct in kind from the telemetry the other browsers might collect by default.
