I am trying to set up sync on my desktop, so I can sync my ipad. When I enter my email address, it says unknown error. I've tried several email addresses.

When trying to set up a sync account, the first thing I have to do is enter my email address. When I begin typing that, I get an "invalid email address" just below it. I understand this is because I haven't finished typing it. Once I finish typing the full address it, the error message changes to "unknown error". I have tried several different email addresses and each time I get the same message. I want to sync my ipad to the desktop.

Which version of firefox are you using? Please update to the latest version if you have not already.

Also are you putting capital letters into the email field? Try using all lower case.

Just ignore that message. It should disappear once you have finished entering the email address.
