As a user, I might not change the config because: * I don’t know there’s a config at all * I know there’s a config, but I don’t know enough about fonts to make a good choice * Most sites override my config anyways (unless I chose an even more aggressive config that breaks websites), so why would I care? * The idea of some site specifying a font does not bother me, even if it’s a web font that will cause an extra 25kb of download. For what it’s worth, I really like fonts and know my way around the Firefox config, but I honestly do not care enough to change the default font because of the last two items on that list.
