Mozilla CEO John Lilly have finally unveiled Mozilla´s plans for the upcoming Firefox 4.0 development effort. John Lilly admitted that Mozilla have to get rid of old habits and to switch to Qt4 as the underlying GUI framework of the new Firefox release as well as to drop the Gecko rendering engine in favor of Apple´s WebKit rendering engine. Furthermore Lilly regret that this decision have not already been made one year ago. So Firefox 3.0 could already use this superior technology. Lilly pointed out that keeping Gecko alive until now was the "biggest mistake since U.S. Navy´s decision to install Windows NT on a warship which had to tow the crippled ship back to port". Google´s choice to use WebKit for its mobile phone framework Android was primary driven by the fact that Gecko´s code base is in a completely unmaintainable state and -- Lilly concluded -- "have more (memory) leaks than a rubber dinghy I have bought on Ebay for 1 USD".
