The Firefox guys at Mozilla
have released the 2nd beta for Firefox 3.1.
"The public beta of Mozilla's first Web browser to incorporate a private browsing mode, is being made available to the general public today, although as before, the organization has yet to make it official." This build also includes the new
TraceMonkey JavaScript engine, and for web content, it's enabled by default. If you want to enable it for XUL/chrome as well, go to about:config, search for 'jit' and set the XUL/chrome option to 'true'.
