Firefox: per-window private browsing test builds available

Firefox's current private browsing implementation features an all or nothing approach. The web browser is either in private browsing mode, which means all windows and tabs, or it is not, which again means that all windows and tabs are not.

The only option that you have right now to display normal windows and private browsing windows of the Firefox browser side by side is to use different user profiles for that.  The Private Browsing Window add-on for the browser improves the process a bit but it is still not ideal, especially if you look at Google Chrome's or Opera's implementation of the private browsing mode. Opera supports for instance private tabs that you can open next to regular tabs in the browser.

Mozilla has been working on per-window private browsing for some time now, and first builds featuring it have now been released. Note that these builds are test versions only designed for the purpose of testing the per-window private browsing mode. They are not related to Firefox's release channels.

You can launch a new private browsing window in the browser like usual. Either use the shortcut Ctrl-Shift-P or click on Firefox > New Tab > New Private Window. A new private browsing window will now be spawned on the desktop without affecting the windows and tabs that are already open in normal mode. If you run the command on current versions of the browser, you will receive a notification that the existing browser windows and tabs need to be closed before the private browsing window can be launched.

The experimental builds are available for all supported desktop operating systems. The developers note that some features are not working yet, and that there are issues that need to be sorted out. This includes the download manager UI which is not connected yet to the new private browsing system, that the new social UI is enabled for private windows, and that the geolocation token is not correctly separated between private and non-private windows.

It is not clear yet when the per-window private browsing feature will be integrated into the release builds of the Firefox web browser. Some bugs and issues need to be sorted out before that happens, but the first big step has been made. You can follow the progress of the development here. (via Sören)

Update: Mozilla has just implemented the private browsing per window feature in to the latest Nightly versions of Firefox.

To select the feature simply click on the Nightly button and select New Private Window from the options. You will then notice that a new private browsing window gets spawned without affecting the other windows that are already open.

      Just a note on Opera Private Browsing.
      If I login to gmail with a ‘normal’ session in its own window, and then keeping that normal session open I login into another gmail account in a private session with its own window I can safely do so and each gmail account is independent and can be used independently. If I open a Third private browsing session I cannot login to another gmail session as the existing private session will interfere with it.

      If I have a normal session and a private session open, each in their own window, I can login to two gmail accounts. If I close my private session window and leave my normal one open when I again start another private session window I remain logged in to the gmail from the previous “private” session.

        It’s pretty obvious that Opera can’t create multiple private sessions, and therefore will interfere with each other.

      We are finally moving towards private tabs?

      Naah, that was probably wishful thinking!
