Safari unable to load ebay.com (and others) after updating to 10.15.7 (19H1417) late Sept

I had the same issue on a lot of sites, including eBay, ... The culprit is clearly Javascript, don't waste your time trying the safe mode, etc. Just do this: download the Safari15.0CatalinaAuto.pkg file directly from Apple’s servers and install Safari 15 using the on-screen prompts.

It solved the issue on my MacBook Pro running Catalina with the latest security update and Safari 15.0

I had rebooted, tried Safe Mode, private browsing, cleared history, cache, cookies, etc. and nothing worked. But downloading and installing the above resolved the issue for me. Thanks!

There have recently been many reports of new problems with Safari. It seems that the recent Safari update has issues. Word has it that Apple knows about the problems and is working on a fix. I assume that it will be released fairly soon. In the meantime, use another browser such as Firefox or Chrome and they should work for you. Also, there are reports that reinstalling Safari and restarting the computer has resolved issues. I hope this helps.

I can’t download

Yep! Download and install worked for me. Thanks.
