Since the vast majority of users are a chromium based browser, doesn't this put the burden on your server pretty much all of the time? why even bother with code to do 2 different things when the other thing is such a niche segment of users?
True; so the server-side rendering is tuned for minimal server load, with the resulting output being heavily degraded. Still good enough for its purpose, and Firefox gets the bonus hi-res thumbnails :-)
