Private Window

I always use Firefox Private Window when I go on the Internet. Today, while I was on Fidelity.com, I was suddenly logged out. When I tried to go back to Fidelity.com using Firefox/Private Window, a dialog box on Microsoft Edge appeared asking me to: "Choice: #1 Do you want to make Firefox to be your default" "Choice: #2 Not Now". Which ever I choice I choose, Microsoft Edge will appear with the two above choices. This has been happening repeatedly for several minutes now, so I tried to reach Firefox Support.

My main problem is I cannot access Firefox / Private Window anymore since I was suddenly logged out of Fidelity.com.

Would you please fix this problem. Also, I already selected Firefox to be my default browser long time ago. Why am I being this question every time I go on the internet using Firefox?

That is strange!

Sometimes Windows loses track of your default applications, so if you haven't already told it you prefer Firefox, it's worth a try.

More specifically:

You mentioned using "Firefox/Private Window" and I'm not sure whether that is a shortcut on your desktop, or the Windows start menu, or if you mean Firefox is running, you right-click its Taskbar button, and then click New Private Window (in the Tasks section of the jumplist). Could you describe that in a bit more detail? Thanks.
