Flash player plug-in
I'm trying to watch TV on my Mac—specifically, Xfinity. The site prompts me to enable the Flash player, which I have installed and updated. However, the Help page gives me instructions that don't match what I see in Preferences.
I should add that I'm using Safari Technology Preview instead of Safari. (Why? Because my bank's bill payer won't work with plain-jane Safari, but it works with Technology Preview. I don't know whether that makes any difference in this instance.)
Xfinity refers me to Adobe's help site (enabling-flash-player-safari.html), which includes a screen shot of a Safari Preferences Websites page. The help page illustration shows a list of Plug-ins. The exact same page on my MacBook does not show any plug-ins at all. I can't enable Adobe Flash Player plug-in if I can't see it in Preferences.
I read a post by Eric Root here in the Community, where he said that Safari, Chrome, and other browsers have dropped support for plug-ins. Okay ... maybe Xfinity didn't get the word? Where do we go from here?
