com.apple.Safari.plist missing: OS 10.14.2
I am trying to disable AutoPlay in YouTube but I can't delete com.apple.Safari.plist becase it's not in my library Preferences folder. I have these plists but not com.apple.Safari.plist. Where has it gone?
com.apple.Safari.SafeBrowsing.plist
com.apple.Safari.SandboxBroker.plist
com.apple.SafariBookMarksSyncAgent.plist
com.apple.SafariCloudHistoryPushAgent.plist
com.apple.SafariServices.ExtensionHelper.plist
