For 6+plus months, I get "popups". The latest shows a box in middle of screen that is in what appears to be another window. The small window has a message "Firewall has defined that your Windows Microsoft system is damaged and irrelevant. ...." plus other junk. No trade marks or anything to identify from whom. In the background, in what looks like another small window but in fact is full screen, it shows System Warning! in blue band around message starting with a "red x Your Windows system is damaged ...." that is partially hidden by the above message.
In the header where normally there is something about the site and an x to close tab, there is only the x. Also, in the address bar, it shows the i in circle, the green locked lock and the address.
Usually, I just shut down Firefox without clicking on screens. I would then restart Firefox which brings up a message "Close Firefox" with the following ? in a circle with message - "Firefox is already running, but is not responding. The old..." with choice boxes to close or cancel. This did not appear in lastest popup.
My settings are that Firefox on closing does not save anything.
The time before was a screen that told me on a specific date, my subscription to McAfee expires, unless.... Only trouble was I don't have a subscription!
The time before that was a McAfee back screen with a small window up front stating "Windows Security Center. Your Mcafee subscription has expired.... " with the choice window "OK".
Only just learned how simple it is to take a screen shot. I used my phone to take photos previously.
Oh and the time before above, there was a popup with Firefox logo and "Dear Firefox user, You re today's lucky visitor for: Feburary 4, 2019 ...".
I have seen multiple times these messages.
I have uninstalled and re-installed Firefox more than once. I just recently did a fresh install of Windows 10 Pro on a reformated M.2 drive. But I have a HDD with most files that I did not touch.
