Private Browsing by PortableApps.com 4.0 has been released. Private Browsing by PortableApps.com is an enhanced privacy mode app that utilizes your existing copy of Mozilla Firefox, Portable Edition. It has specialized settings, a flash blocker, a privacy-enhancing blocklist, ad-blocking, improved separation from the local PC, a separate profile and a custom icon so you can easily distinguish it from your main Firefox Portable profile. It even has its own separate set of bookmarks. It's basically a more-advanced private browsing feature than those included in major browsers that can even be customized further by advanced users. This release disables all Firefox telemetry by default, adds ad-blocking, and updates the included extensions to the latest versions. It's packaged in PortableApps.com Format so it can easily integrate with the PortableApps.com Platform. And it's open source and completely free.
Update automatically or install from the portable app store in the PortableApps.com Platform.
