Unknown error when trying to set up Firefox Sync

Posted

I try to set up Firefox Sync but as I fill in my e-mail address on the first line i first get the message "invalide e-mail account" (or similar) but then when I continue to complete it with www@yyy.com it just says "unknown error". I have tried several different e-mail addresses on two different computers but the same annoying unknown error message keeps coming up. What am I supposed to do about that?

You can try to reset the sync prefs on the about:config page.


Try to create a new profile as a test to check if your current profile is causing the problems.

See "Creating a profile":

If the new profile works then you can transfer some files from an existing profile to the new profile, but be careful not to copy corrupted files.
