Problems with flash player when using the latest chrome version

I watch HD Prime using the chrome browser and still can. But in the past I've always been able to add and store sites to the 'always allow flash player' option in google settings. so when using HD Prime, for example, the video automatically plays.  BUT, since Chome latest update the options have changed. It's still defaulted o 'always ask' but now there's no option to store the web pages you want to use with flash player. Instead, every time you select a web page, such as HD Prime, you must manually select the 'allow flash player' option first, before anything will play. I also had the same problem when trying to watch something on firstonetv as well.

Does anybody know of a way around this to enable flash player to be used on selected/chosen sites automatically?
