How do I quit Safari? The Quit Safari option is not hi-lited

If you're using a mac: https://support.apple.com/en-us/HT201276

If you're using a macbook, you can click the safari icon with 2 fingers in the trackpad, then select "Quit". It's just a shortcut but the link above works in macbooks as well

Command and q key quit the frontmost app.

Command ~ toggles between apps and a tap on the Q key will quit that app.
