When I register my Firefox Sync account (Firefox Mozzila 24.0) in first window I am asked to enter my e-mail, password, the password confirmation, server, to put the tick if I agree with Terms of Service and Privacy Policy. But there is no capcha in the window although instructions in https://support.mozilla.org show that the captcha should be). And when I press "Next" button there is error message that the capcha word is wrong. I reseted Firefox settings to the default but the problem was not resolved. Can you please help me wth the issue? What I should do the capcha to be visible in registration window?
