I have tried signing up for an account at a http://www.spoj.com/register/ using Firefox, but no matter how hard I tried, I couldn't get the correct captcha.
To my surprise, when I tried the same registration page in Chrome, a different captcha came up.
Is there any good reason behind why it's dead simple in Chrome, but almost impossible in Firefox?
