For the last four years, every time I’ve asked a Mozilla person if Firefox was going to come to Apple iOS, the answer has always been no.
Apple’s own restrictive policies will not allow another rendering engine and that means that Mozilla’s core Gecko rendering engine is not an easy option. Mozilla is now investigating another route, by building a new browser – codenamed junior.
Since Marc Andreeson and Netscape, Mozilla and its forebears have always been Gecko based. Junior will be the first Mozilla browser tech to use WebKit.
