many of thew links with the "eternal link" icon actually trigger a download popup and not a navigation. Should these links use that icon? This is visible in "resources/fonts.html"
one link in "visuals/product-identity-assets" has a download icon to represent this, should we use that everywhere?
should the external links open in new tabs?
in "visuals/iconography.html", there is a link "Firefox icons template" which leads to our page "resources/icons.html#icons-template" which then tells you to open an external "icons template". Should the first link go there directly?
