Safari hangs on many programs

I could open Yahoo Finance and Seeking Alpha websites on this Mac.

If you have not tried any of these suggestions, please try it.

Startup in Safe Mode   https://support.apple.com/lv-lv/HT201262

Login to your account.  Launch Safari. Try opening the sites.

To exit Safe Mode, click   in the menu bar and choose “Restart”.

Are you running any anti - virus programs? Using a VPN?

Try setting up another admin user account in System Preferences/Users & Groups to see if the same problem continues.

If it works in the Safe Mode, try running this program when booted normally and then copy and paste the output in a reply. The program was created by Etresoft, a frequent contributor.

I'm running a brand new iMac Pro with macOS Catalina 10.15.3 and have the same problem. Today's "stalls" on Ebay, and Fender, Google, and Yahoo websites, --bring my Mac to a standstill from which only a hard restart can recover. When I try one of these sites the status bar gets to 10% of loading and stalls. Clicking outside of the Safari window gets the beach-ball-of-death. I've tried all the recommended fixes, safe mode restarts, and even re-installed my system software. I have no Safari extensions running and have scanned for malware, viruses, etc. I'm totally at a loss.

Try running/posting the Etrecheck program. If the log won’t post, try posting it in Pastebin and provide a link in a
