My wife runs firefox on a Surface with W10. When she opened it today the homepage looked like the control panel and a message was displayed at the bottom of the page that stated "Windows 10 Build is corrupted....". A dialog box displayed asking for login and password credentials. The only way to get out of this was through task manager. I uninstalled and reinstalled firefox and that seems to be working for now. However, this is the second time in a week that this has happened and I would like to know where it's coming from and ensure that it is removed completely from firefox.

Separate Security Issue: Update your Flash Player Note: Windows users should download the ActiveX for Internet Explorer. and the plugin for Plugin-based browsers (like Firefox).

Was this message part of Firefox if you would move the Firefox window around?

Next time try to catch this in a screenshot.
