Hi, if you mean when you right click on the Firefox Taskbar icon, under Tasks, you see the purple 'New private window' option - that is normal, and if you don't want to use it, you can just ignore it. Firefox should open by left clicking in the usual way.

If you are getting a private window option when you right click the Firefox Desktop icon, you may have a corrupt shortcut icon. So in the Start Menu, right click on Mozilla Firefox in All Programs/Apps > Send to > Desktop (create shortcut). You should now have a clean shortcut on your Desktop. if it's OK, you can now right click on the old Desktop icon > Delete.

Thanks for your reply. I'll try to ignore the purple flag as you suggested. Why I questioned it is that I never saw it until a few days ago, no matter how many times I might've right-clicked the taskbar icon in the past. Is it part of a recent update where they just added an easy way to access a new private window?

I'm always puzzled when it's a change I myself didn't make. In this case it's also because I don't fully understand the functions of Private Browsing, so I've consistently avoided it. Perhaps I misunderstood that in order to use Private Browsing, I lose my "Don't remember history" ability, which is a must. I'll appreciate anything you can add. Thanks again.

The image used for Private Browsing from the Task Bar was changed for Firefox 42. Previously the image wasn't colored purple, more like a lighter blue color.

Thanks. I probably never noticed it before the color change.
