"Checking your browser before you access eBay."

Hangs on this page when I click on a listing. It did this a couple of weeks ago then it went away. It's happening again in firefox on a mac, all up to date with latest OS, latest firefox, tons of memory, etc. Doesn't happen with Safari, only firefox. 

"Checking your browser before you access eBay.

Your browser will redirect to your requested content shortly. Please wait..."

A half an hour later and I'm still waiting.

If the problem is with Firefox, use another browser. No sense waiting for a hung page to load beyond a minute or two.

If you are trying to diagnose the issue, are there any differences between your Firefox setup and your Safari setup? Add-ons in one but not the other? Blocking scripts or third-party cookies in Firefox? Do you have the latest version of Firefox for your operating system?

Using Firefox on a Windows 10 machine, I am not having that issue -- I see that message from time to time but it goes away and is replaced by the page I am trying to reach.

Many eBay pages have a "Tell us what you think" link, or else a "Feedback" / "Comment" / "?" icon in the lower right by the scroll bar. Those can be used to report page or site issues to eBay developers.

Not Firefox, eBay changed what is in there Cookies

Go to settings and remove the eBay Cookie you will have to sign in again afterwards but the issue seems to be fixed after you get the new Cookie from eBay.

It worked for me.
