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?

More then likely it has to do with the amount of times you have previously solved a ReCAPTCHA before. If I delete Google cookies from my browser I will get the harder to solve ReCAPTCHAs at first, eventually it will turn into the easier ones.

If you are logged into a Google property you might also get easier to solve ones, since they know you at least have an account and previous account activity.
