Up until a few years ago YouTube gave users a choice of using either Flash Player or an HTML5 player to play videos. HTML5 eventually became the default, but browsers and operating systems which lacked HTML5 support for all of the video codecs and resolutions that YouTube uses would automatically fall back to Flash as necessary.
Then they ended the automatic Flash fallback; as long as your browser supports some HTML5 playback, that's all you'll get, even if it means you can only watch videos at one resolution (usually 360p). But with a browser extension you could still force YouTube to play via Flash, as it would on old browsers and OSes which lacked any HTML5 support. You could even still watch YouTube in Windows 98 using Flash Player 9, with low resolution and limited functionality.
But now as of a few days ago, YouTube has dropped all support for Flash Player, even as a "last resort" fallback. As the author of one of the browser add-ons to force Flash playback noted:
"July 27, 2017: YouTube has made changes and it looks like it's no more possible to watch videos using Flash Player. Not really surprising since Adobe has announced the end of Flash ( https://blogs.adobe.com/conversations/2017/07/adobe-flash-update.html ). So please stop sending me emails, there's nothing I can do, add-on is working as expected, it's just YouTube that forces the use of the HTML5 player. Open the console (Ctrl + Shift + K), type "yt.msgs_.YTP_HTML5_FLASH_DEPRECATED" (without quotes) and press Enter."
I know Flash is a security risk and most people are glad to get rid of it, but older PCs -- even some Core 2 Duos -- will often bog down quite badly and drop a lot of frames when beginning to play any YouTube video via HTML5, even in Windows 7 64-bit, so it was nice to be able to use one of those browser add-ons to force it to use Flash, which played much more smoothly on older PC hardware.
