speed, synchronisation, integrated flash support, .webm, 60fps videos, chromecast, tab muting
firefox has almost identical speed, it has synchronization, it has flash included by default, it has .webm, it has 60fps video. chromecast is obviously chrome only. tab muting is an unfortunate loss yes.
The only thing I really, REALLY miss from chrome is WebP support. It's a file format vastly superior to jpeg and png in terms of compression and firefox literally refused to implement it because it's "new." IT'S NOT NEW NOW GUYS.
