why are wangblows browsers all so shitty

chorme - legendary bloat, uses a gig of memory to work and more security vulns than IE 9
intenet explorer - actually gotten better but still has some major issues
firefox - going to hell, also bloated and runs like shit on lower performance computers, and it doesn't use native windows toolkits which makes it even laggier in some places
safari - lol
midori - broken
opera 12 - redeemable but heavier than mckailey
opera 18 - retarded dumbed-down bullshit
