Adobe Flash should've died off long ago, but sadly, the world has been slow to move to HTML5.
Adobe Flash is a total resource hog and works very poorly on touch devices, it just wasn't meant for touch. Apple was right to declare it a thing of the past, and Microsoft fell suite with WIndows Phone, and even Google has given up, as Android 4.1+ no longer natively supports Flash.
Microsoft also almost dumped it with Windows RT/Metro, but later decided it would be permitted to run on certain sites (but it defaults on HTML5, should it be available). I know you want to enjoy your Flash content and all, but the world needs to get with the program. It's time to move on from the past into a brighter (less of a resource hog) future.
