The only browsers I recall having to had to install Flash on was Firefox 59 (ESR), not though some come with it disabled by default which is instantly enabled once you choose.
Running this test, http://get.adobe.com/flashplayer/about/ shows that besides FF ESR, Firefox Quantum portable, Basilisk, Waterfox, and Chrome portable (new) all say "You have version 32,0,0,321" installed. Edge says You have version 32,0,0,255.
But most plan to phase it out.
WP says, Google Chrome, Internet Explorer 11 in Windows 8 and later, and Microsoft Edge come bundled with a sandboxed Adobe Flash plug-in.[6][7][8][9][10] https://en.wikipedia.org/wiki/Adobe_Flash_Player
According to Google, the current version of Chrome has Flash installed.
However, you need to go through a 5 step process to activate Flash on a specific page - with Edge, that is automatic, as far as I know.
My original comment was based on the first Google information box that popped up. It explicitly said Flash had to be installed on Chrome.
Bottom Line - I was just trying to help out the guy who could not make Flash work on Windows 10. All of my information about Chrome comes straight from Google.
