I recently switched from google chrome to firefox and have been trying to set up Firefox Sync. I get the following message after creating a Firefox Sync account. "Sorry. We’ve locked your account. The confirmation email we sent to csuttles@triggeredstudios.com was returned and we’ve locked your account to protect your Firefox data." The email is total valid, I can send a receive emails to and from it without issue. My email address is a custom hosted domain using tutanota.
