A couple of days ago, I had to completely reset my laptop (Lenovo Ideapad 110), and now I'm having a problem trying to sign in to eBay.

I've entered my details fine, then eBay asks for verification via Captcha - which I pass fine. However, Firefox pops up a 'need to resend data' window, and when I say OK, it essentially just refreshes the page, meaning I have to do the Captcha again, which brings up the window again - and so on until I just quit.
