Currently, when Firefox detects an available update, it lets users know and if users do not change the default setting or agree to install it, the browser launches its updater program. Then program downloads the update, applies it to Firefox, and restarts the browser. To empower Mozilla more control on forcing users to use ‘latest’ version of Firefox, Mozilla came out with a stealth method: just download the new version in the background without informing users, and upon the next relaunch of Firefox, the old Firefox will be swapped out with the new one.
"While many IT security systems will have to be reconfigured to allow background updates to Firefox--which is not a good thing in the first place--there is danger that hackers could subvert the update system to allow them back-door access to the users’ computer," according to Philip Lieberman.
