chrome://settings/content as replacement to chrome://plugins/
Don’t worry you still can control your content setting by accessing page chrome://settings/content from chrome.
chrome://extensions/
To access your extensions, remove, on and off your extension for Chrome. Plugins and extensions seem almost the same but it’s not. If you see additional icon on your Chrome browser then it is an extension. Plugins will not affect the Chrome appearance it will not showing any icon.
chrome://settings/help
