Stats
Is the decline in market share for Firefox due to the stats including mobile devices (essentially locked down to Safari on iOS and largely only going to be Chrome on Android) or are they excluded? If mobiles are included I would expect Firefox's share to be distorted as they cannot realistically operate on those platforms.
From looking at the W3Counter link only 30% of the platforms were desktop OSes. I'd be more interested in the breakdown here as platform policies on mobiles can ruin your accessibility meaning they're never likely to compete.
