Mozilla released Firefox 3.1 Beta 2 on Monday with many new features such as the anticipated private browsing mode, a new Tracemonkey javascript engine and new functions that make it easy to remove specific portions of Web history.
The private browsing mode helps users to surf the Web without leaving a trace so that when your colleague sits on your computer, he or she will not be able to view browsing history. If your browse normally, you would have to keep deleting your history when you're away. However, sometimes you may be forgetful. Do note that this useful tool isn't like a free proxy site which enables you to surf blocked sites by your ISPs.
According to Mozilla, the Firefox 3.1 Beta 2 "is a public preview release intended for developer testing and community feedback". Other features and changes include support for video and audio built into webpage, support for web worker treads, removed the new tab-switching and preview behaviour based on feedback from Beta 1 users.
