HELP! I foolishly upgraded to Safari 12.0, now my extensions are broken! (RES and JS Blocker). I WANT MY EXTENSIONS. How do I download old versions of Safari? I don’t want Safari 12. Apple used to host old versions of software all over their website, but in this brave new world of apple this seems to be gone! Restoring in Time Machine won’t work for reasons that I COMPLETELY DON’T UNDERSTAND! HELP!
