I could'nt log in so I tried few more password combinations... Way too much I think :c

Dear Sirs, Today I've been trying to backup my bookmarks, settings, etc. in Firefox Sync. I forgot my password, so I was trying few times with different password combinations. When I gave up, I tried to set new password via email. I got email with external link connecting me to website with password recovery (or however its called). I set a new password but I still can't log in (few hours later now). When I'm trying to log in, I'm getting message in my native language (so its little bit hard to translate), but it would be something like "Attempts limit exceeded". At that point I'm stuck. Setting new password does'nt even help.

P.S. I'm sorry for my English. I hope you will understand what I mean & help me to solve this problem :)
