From the subject line - I keep getting this error when trying to use Firefox Sync on my Windows 10 desktop. Sync already works on Mac and Android, and I've already verified that I'm using my primary email to login.

I managed to get Sync to work by opening a Private Browsing window and signing in using the same email and password.
