@martin Should also add that elementary OS's native browser, Epiphany (based on Gnome Web), syncs with Firefox accounts—so you don't even need Firefox, technically!
(IMHO Epiphany is a totally decent browser if you don't need a ton of extensions—comes with built-in adblock, lighter than Chrome & Firefox.)
@martin it uses your Firefox account, so yeah, it syncs with both FF & Epiphany. E. g. when sharing a link via Firefox mobile I can send it to Firefox desktop, or Epiphany.
