User level: Level 1 (6 points)Ever since my MacBook Air upgraded to 15.7.9 last evening, I can't use FaceBook without it crashing instantly. (Or rather, freezing up.) Is this happening with anyone else? What can I do?

Hi,
This instant-crashing issue after updating to macOS Sequoia 15.7.9 is usually caused by a conflict between the updated browser cache, outdated web extensions, or Apple's WebKit rendering engine struggling with Facebook's heavy scripts.
Try different browser.

Thank you so much for this reply. It's so very frustrating though - I had to completely quit using Safari on my old iMac several years ago, and now I need to quit using it on my 6-year old MacBook? What good is Safari if it can't keep up with the demands of all other software/internet-sites out there?
