Safari window freezes, new window works

I will be reading a newsmag on Safari when the window freezes. Clicking on stories does not open their pages.

But if I open a new Safari window and go to the same site, the page works. So I will see two identical pages side by side, one dead and the other live. Why?

iMac 24″, macOS 15.6

It is hard to say "Why" without doing some digging.


1) If you are still running macOS 15.6 Sequoia and Safari 18

You should update the iMac to macOS Sequoia 15.7 and Safari 26.

see > What's new in the updates for macOS Sequoia - Apple Support

for more info see > About the security content of Safari 26 - Apple Support


2) Then if you are still having an issue after updating to Sequoia 15.7 and Safari 26.
