My safari will not allow me to open any sites in their full detail. How can can this be fixed?

Reboot into Safe Mode, and try again.

If there are add-on security apps, add-on anti-malware apps, add-on VPN apps, add-on cleaner apps, add-on ad-blocking apps, any added Safari extensions, or similar apps, remove all those per the vendors’ instructions, and try again.

Clear Temporary Internet Files in Safe Mode:

Boot into Safe Mode and then Clear your Temporary Internet Files of Safari:

1. Booting into Safe Mode: [hold down shift upon boot until the login screen appears]. See if this is still an issue. Safe Mode lets items run as default, without changes whatsoever. That is possible because caches of your macOS are temporarily disabled while in Safe Mode.
2. Clearing your Temporary Internet Files (Cookies & Cache) of Safari: Cookies perform remembrance of certain site-entered data. Whereas Cache keeps a snapshot of the last time you visited a site.  Use this Link: Clearing History and Cache - Apple Communities
