If you run Firefox (or any of the forks), run uBlock Origin. Many ads are malicious. If a site won't open or won't function properly because you're using an ad blocker, leave the site. It really is as simple as that.

That's eBay and Amazon out then. Actually I have Chromium installed for just those two sites and close it as soon as I've ordered.
@pthane I no longer have an Amazon account but when I did, I was able to use the site with an ad blocker.

I think it's the pop-up blocker causes the problem.
