User Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:54.0) Gecko/20100101 Firefox/54.0 Build ID: 20170608105825 Steps to reproduce: I recently updated my Firefox to the version 54 and newly installed duckduckgo add on. Actual results: Since the update I have not been able to log in into Firefox sync, pockets and when I try using VPN the browser is stuck at "performing TLS handshake" . I have received the confirmation email but the link does not open. Expected results: The Account should have been verified and i be able to log in to Firefox services and when i use VPN the browsing should continue as regular.

John or Jon, sounds like potential TLS issues when accessing the auth-server, have either of you seen this sort of thing before?

Hi :ashwinphadke12, thanks for reporting this bug! The first thing I'd like to verify is that your Firefox TLS settings are configured correctly; could you visit https://www.ssllabs.com/ssltest/viewMyClient.html and take a screenshot of that page?
Also try to disable `network.tcp.tcp_fastopen_enable` via about:config if that is enabled.

:ashwinphadke12 - Do you get the same error message when you disable your VPN and access that page?
