Definitely did. Just a bit of joking around. You know the trend I guess how it's boxes but the corners with aggressive radius that in a long narrow box like say, an address bar will look like two semicircles at either end. Aka sausages.

Like for example take your picture. Instead of the Download button still looks like boxes with rounded corners, just increase the radius until they become semicircles. There was plenty of short sausages in the Firefox video ad from what I recall.
