Firefox 12 arrives just one month and a half after Firefox 11, and it brings minor functionality and stability improvements.
The newest Firefox version does not mention anything about improving resources or performances, which are aspects criticized by users who own weaker computers.
However, Firefox 12 will be updated without us confirming the security dialogue displayed b User Account Control. Actually, Mozilla intends to switch to an automated updating system for Firefox, in which new versions of the web browser are installed without user intervention as soon as they become officially available.
The in page search feature was improved, and the download manager allows you to automatically download from added URL addresses.
The list of improvements also includes an updated set of media controls for the video rendering feature through HTML 5 API.
