Firefox 12 released with UAC-less update system on Windows

Mozilla announced today the availability of Firefox 12, a new version of the popular open source Web browser. The release brings some minor incremental feature improvements, a number of fixes under the hood, and a significant change to the browser’s update system on Windows.

Ever since Mozilla transitioned Firefox to a shorter development cycle, the organization has been working to make browser updates less intrusive and more seamless. The eventual goal is to make updates completely silent, performing them in the background without user intervention.
