"Internet Plug-ins" option missing
I am a new MacBook Pro user. I just purchased it a couple of weeks ago. Love it. Its different than windows. I am having trouble finding the "Internet Plug-ins" everyone tells me to go to to enable the flash player that does not work on certain websites like mint.com. I go to safari preferences, but the Internet Plug-In options are neither in the security settings, nor the website area on the bottom left. HELP! I can not get this enabled. Thanks.
I have a MacBook Pro 2018 & 10.13.4
