According to Mozilla's own research[1]: how many sites in your mobile Webkit browser crawl use at least one of 'transition', 'transition-timing-function', 'transition-duration', 'transition-property', 'transition-delay' (ignoring prefixes)? 1245 / 30087 = 4.13% how many use them only with -webkit prefixes (no -moz or unprefixed versions of the properties)? 336 / 30087 = 1.12% how many use them only with -webkit prefixes and unprefixed (no -moz versions of the properties)? 365 / 30087 = 1.21% Is it really that serious an issue if it only crops up in 1.12% of mobile sites (where webkit has the overwhelming marketshare).
