(In reply to Thomas Wisniewski [:twisniewski] from comment #4) > Perhaps Chrome is just initially zooming to fit all of the content? For instance, citilink.ru does not specify any `meta viewport`; it just sets the width of its header, footer and such to `1450px`. Upon loading the page, Firefox ends up zooming in so some content is off-screen (with `window.innerWidth < 1450px`), while Chrome shows the full page zoomed out (with `window.innerWidth == 1450px`). This deserves further investigation; it sounds like the mechanism added in bug 1423709 for determining the initial zoom level may not be working correctly on this page.
