Форум поддержки Firefox

Hi:

I am using the Safari browser on my Mac. Suddenly when I wanted to login into the Firefox account I got the 500 Error message that I pasted in the Subject. I am a new user of Firefox, just switched from Safari and I am not computer savvy...

I cannot login, I cannot create another account...

I hope I do not have to go back to Safari.... I have no idea what might cause this problem and what to do. I hope that somebody has the answer. Thanks in advance.
