Safari 16 "a problem repeatedly occurred.."

I recommend use another browser, safari is the new Internet Explorer, I highly recommend Opera

I've been having this exact same problem with Safari. Tried all the remedies. In my case, Safari is only doing this on my Mac Pro (Late 2013), not my Mac Book Pro or my iMac. They're both fine. Firefox is having no such issue, just Safari. I have a direct Ethernet connection and 1Gig internet service. Also, Mail prompts me to enter my password for one of my mailboxes but the box to enter the information comes up blank with no way to enter anything. Both problems started after the most recent upgrades. I think there's a glitch in Java Script because, when I turn it off, YouTube loads just fine but, of course, won't play any videos. The problem reoccurs when I turn JavaScript back on. I even did a clean reinstall of Mac OS. Didn't help.
