Re: “That is simply not true. I use at least 5 browsers with flash.”
I do not understand your post.
With Windows 10 and Edge, you do not need to separately download and install Flash Player to use it. You just check the Flash Player box in the Edge settings. I’m using Flash right now. It’s the default setting.
With Windows 10 and other browsers, you do need to separately download and install Flash Player.
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
And I am running W.10. Thank God for what we can use for His work and will.
