meteorit writes "Mozilla has been working on a mobile version of Firefox since last year, and is now looking to repeat the success of Firefox on the PC. Although development seems not to have been completed, it is known that informal negotiations have already started with mobile network operators. Firefox Mobile is scheduled to be launched by the end of the year and the inaugural version will be compatible with the Linux and Windows Mobile operating systems. Work is already underway to determine what the browser's UI will look like. In the meantime those negotiations seem to be hitting 'brick walls', as cellphone operators resist the intrusion of the open web onto their platforms."
