Diverse opties
Debug menu inschakelen: This option shows or hides a Debug menu in the Safari menu bar.
Ontwikkelaarsmenu inschakelen: Safari has hidden features that can be turned on or off with this option. You can use this menu to open the current webpage in another browser, change the User Agent, display the Web Inspector, turn on or turn off some functions, and so on. This option also adds an Inspect Element item in the shortcut menu of Safari. By default, the Web Inspector appears in an individual window, but it can be merged with the displayed page by clicking either of the two leftmost buttons in the toolbar of the Web Inspector.
DNS prefetching uitschakelen: Safari integrates a significant feature: DNS prefetching. Its purpose is to speed up the loading of webpages, but this prefetching may occasionally result in slow performance, partially loaded pages, or pages not being found. You can use this option to turn on/turn off the DNS prefetching.
