Is your Firefox set to start up automatically in private mode? With that setting, the private windows are not specially marked (no mask icon, no special start page). Please check on the Options page, either:

  • "3-bar" menu button (or Tools menu) > Options, in the left column click Privacy
  • Type or paste about:preferences#privacy in the address bar and press Enter to load it

If the selector says:

  • Firefox will: Never remember history - Firefox is set for automatic private browsing
  • Firefox will: Use custom settings for history - if the box is checked for "Always use private browsing mode" then same as above

Hello romccr, please try to see if you have the same behavior in firefox safe mode.

If you have the same behavior in firefox safe mode (the New Private Window does not work) then try a Clean reinstall. This means you remove your Firefox program files and then reinstall Firefox. This process does not remove your Firefox profile data (such as bookmarks and passwords), since that information is stored in a different location.

To do a clean reinstall of Firefox, please follow these steps: Note: You might want to print these steps or view them in another browser.

  1. Download the latest Desktop version of Firefox from mozilla.org (or choose the download for your operating system and language from this page) and save the setup file to your computer.
  2. After the download finishes, close all Firefox windows (or open the Firefox menu New Fx Menu and click the close button Close 29).
  3. Delete the Firefox installation folder, which is located in one of these locations, by default:
    • Windows:
      • C:\Program Files\Mozilla Firefox
      • C:\Program Files (x86)\Mozilla Firefox
    • Mac: Delete Firefox from the Applications folder.
    • Linux: If you installed Firefox with the distro-based package manager, you should use the same way to uninstall it - see Install Firefox on Linux. If you downloaded and installed the binary package from the Firefox download page, simply remove the folder firefox in your home directory.
  4. Now, go ahead and reinstall Firefox:
    1. Double-click the downloaded installation file and go through the steps of the installation wizard.
    2. Once the wizard is finished, choose to directly open Firefox after clicking the Finish button.

More information about reinstalling Firefox can be found here.

WARNING: Do not use a third party uninstaller as part of this process. Doing so could permanently delete your Firefox profile data, including but not limited to, extensions, cache, cookies, bookmarks, personal settings and saved passwords. These cannot be easily recovered unless they have been backed up to an external device! See Back up and restore information in Firefox profiles.

Please report back to say if this helped you!

Thank you.

By the way, what do you mean by "does not work"? No new window appears, or it's not a private window?

Tried launching New Private Window in safe mode. Same response....it just gives me another non-private window. Uninstalled Firefox and reinstalled per the above instructions with the same result.

Thanks jscher2000. I found it was set to always use Private Browsing Mode. Turned it off...reset and I now get Private Mode manually as desired.
