Today when I opened Firefox in Private Window I was greeted with some kind of pop up type feature in the middle of my private page about changing the color of Firefox. I have never seen this before so I closed the window and it made me think that I had malware which I promptly closed Firefox and ran Norton and Malware Bytes which were neg. I opened Firefox again not using Private Window and it opened to Firefox default page instead of the homepage I had designated as being Bing. So I had to now go into settings and reset my home page which is stable. What is going on with Firefox? Will we be seeing these option windows appear when we open Firefox like to change Firefox colors or something else? Is there a purpose of changing my homepage back to default Firefox? What other things have been messed with that we do not know about.
