My Mac n longer has a “Quit Safri” option. How do I get it back?

The directions from Previous posting.

Or Apple Icon on Desktop pop down menu and Look for " Force Quit " which presents another window and choose Safari >> Force Quit. It may offer an Alert - choose Yes.

This no normal behaviour so do check for updates to Big Sur as your profile is showing an out dated version 11.2. The present version is Big Sur 11.5.1 Also, make A Time Machine Backup before attempting.  A Time Machine Backup  is very useful and can be used to Revert to Previous Working macOS.

Restart your Mac.

If rebooting your Mac doesn’t fix things, see if the problem still happens in Safe mode (hold the shift key down at startup). It can take much longer to safe boot (10 min) so be patient.

How to use safe mode on your Mac - Apple Support 

Safe mode forces the OS to clear certain caches and logs and do other miscellaneous housekeeping. It's non-destructive to user data so is safe to do. Very often certain weird software behavior is corrected by simply logging in this way as a troubleshooting method. When you're in safe boot, the machine will not be at its best performance, especially with graphics, but that's normal.

Does the problem persist while in Safe mode?

Exit safe mode by restarting your Mac normally and re-evaluate the issue again.
