eBay won't let me log in, strange message

Hi,

 

All of a sudden I am getting this message.

 

Pardon our interruption...

As you were browsing eBay, something about your browser made us think you were a bot. There are a few reasons this might happen:

You're a power user moving through this website with super-human speed.
You've disabled JavaScript in your web browser.
A third-party browser plugin, such as Ghostery or NoScript, is preventing JavaScript from running.

 

First it popped up when I was trying to sign out. It would not allow me, so I just closed the browser, deleted all cache and cookies etc. Then when I tried to log back in I got the same message. It will not allow me to log in. Javascript is enabled in my browser and as far as I no I do not have any Ghostery or NoScript plugins running.
