Firefox developers incorporate Private Browsing mode
Firefox developer Ehsan Akhgari writes that the Mozilla Firefox developers have now incorporated the "Private Browsing" feature which was originally intended for the current release, into the nightly builds of Firefox 3.1. According to his blog posting, the nightly build for the second beta of the next Firefox version now offers a "Private Browsing" menu item that allows users to start a web browsing session that doesn't leave any traces on the local system's hard disk.
The feature is similar to that in Safari and in the current pre-release versions of Google's Chrome and Microsoft's Internet Explorer 8. It was originally supposed to be a part of Firefox 3, which has been available since June. The new privacy feature can be tested in the pre-release version of the second beta now available to download for Windows, Mac OS X and Linux. Nightly builds are even less suited for production use than an official beta release. It is recommended that users only use nightly builds for testing purposes.
