hm, that's simple 'does this use case run 1 thing particularly well.'
EXIF rotation and ability to use gstreamer for video are massive feature improvements that may result in slower page generation, but the returns are far more significant.
not everything has to be 'better, faster, smaller' making things generally better with _no_ regressions is difficult enough.
Yeah, I phrased that poorly (was fighting with links and not thinking about my words too carefully). I didn't mean to knock the release by any means. I was only making the observation that there didn't appear to be much in the way of asm.js performance improvement this time around.
And you're absolutely right; the fact that there are additional features/improvements and I get to keep the same (awesome) performance from FF 25 is very impressive and laudable. I can enumerate several FOSS projects for which this sort of thing is an issue.
