Comments concerning Microsoft Edge Browser for Windows 10 and HTML5

I use several plug ins with Internet Explorer 11 and Chrome. Microsoft Edge was released with Windows 10. I contacted Microsoft Support directly and spoke with management. They said the Edge browser does NOT support plug in extensions currently, but will about April 2016. Lastpass password manager is a plug in. Java is a plug in, and Flash is a downloadable plug in required to run Flash on websites. Flash Player is integrated with Microsoft Edge in Windows 10, so you do not need to install Flash Player. However, had this not been the case, Edge, being that it does not currently support plug in extensions yet, Flash would not work with Edge, and thus many websites would not work. You are still not addressing the issue that Flash is going to be phased out for the HTML 5 because it is more up to date and secure. Flash has long been exploited too much and may be surpassed by better and more secure technology.  I understand that Flash does not work on the Windows phones, but if that is why SOME people do not buy them, they are sadly ignorant and misinformed that IE is actually a better browser for the smartphone than the other browsers, and a better phone, especially because it works along side a more realistic operating system connected to your Windows 8.1/10 version on your computers. I got rid of Apple and Google Android phones. They are pointless and irrelevant, and that is going to only stay the same in the future no matter what sales and market is like. The articles that I have studied, and also concerning technology is all smartphones are going to phase out Flash eventually or sooner, and the standard will be HTML5. That is what I am gathering.
