Using latest Firefox (Fx 35) I browse https://www.mozilla.org/en-US/firefox/desktop/tips/ and the tabs do not appear under the subhead.
Showed a few others and they could not replicate issue.
Tried resizing screen, zoom in, out...
Looks fine in Chrome.
Mike, just a guess but do you have any Ad-block plugins installed?
If I hide the div `#share-nav-wrapper` it matches your screen-shot, so maybe an add-on is hiding this as it thinks it's ad/social related content. If it is an add-on causing this and the navigations shows when you disable it, we should probably just rename the div to stop this happening.
Confirmed the issue is ad-block

Mike, could you test on prod to see if this issue still exists? We can then mark this one as resolved.
Looks good on prod with adblock plus enabled. Thanks Alex!
