Firefox's private browsing feature debuts in latest Minefield build
Back in September, the Mozilla wiki provided clues that private browsing was indeed back on the radar for version 3.1 of Firefox. With the release of beta 2 looming, anxious testers can preview the feature by downloading the latest nightly build.
To enable the feature, click the tools menu and then click private browsing to enable it. You'll be asked to confirm your selection and restart the browser. Eschewing any blatant notification that you've activated the feature, Minefield will simply add (Private Browsing) to the application 's title bar.
You'll also see a notice that private browsing is enabled and what exactly that means: browsing, search, form, and download history will not be saved, nor will cookies or temporary files. Any new downloaded files or bookmarks will be retained.
Eshan Akhgari has more information available about private browsing, and thankfully he's put forth a possible application that doesn't directly involve NSFW surfing: "an example scenario would be looking for a new employer while at work."
